| CVE | CVSS | EPSS | Vendor, product | Description | Modified |
|---|---|---|---|---|---|
| CVE-2026-7504 | 8.1 high | 1.0% | redhat, build_of_keycloak | A flaw was found in Keycloak's URL validation logic during redirect operations. By crafting a malicious request, an attacker could bypass validation to redirect users to unauthorized URLs, potentially leading to the exposure of sensitive information within the domain or facilitating further attacks. This vulnerability specifically affects Keycloak clients configured with a wildcard (*) in the "Valid Redirect URIs" field and requires user interaction to be successfully exploited. The issue stems from a discrepancy in how Keycloak and the underlying Java URI implementation handle the user-info component of a URL. If a malicious redirect URL is constructed using multiple @ characters in the user-info section, Java's URI parser fails to extract the user-info, leaving only the raw authority field. Consequently, Keycloak's validation check fails to detect the malformed user-info, falls back to a wildcard comparison, and incorrectly permits the malicious redirect. | Mon 26 Oct |
| CVE-2026-9800 | 8.1 high | 1.0% | redhat, build_of_keycloak | A flaw was found in Keycloak Policy Enforcer. This vulnerability allows any authenticated user to bypass all authorization policies, including role, scope, and User-Managed Access (UMA) permission checks. By including the configured access-denied page path within a request URL, either as a path segment or a query parameter, an attacker can gain unauthorized access to protected resources. | 20 Oct |
| CVE-2025-23368 | 8.1 high | 1.0% | redhat, wildfly_core, data_grid, jboss_enterprise_application_platform | A flaw was found in Wildfly Elytron integration.

| CVE-2026-12542 | 7.8 high | 1.0% | redhat, theforeman, satellite, foreman | A flaw was found in Foreman. The foreman-tail utility is vulnerable to OS command injection due to the unsafe use of the eval command. The script takes user-supplied arguments and incorporates them directly into a string that is then executed by eval to expand file paths. Because the input is not sanitized or quoted, a local attacker can inject shell metacharacters (e.g., ;, &, |) to execute arbitrary system commands. | 16 Oct |
| CVE-2023-42753 | 7.8 high | 1.0% | linux, redhat, linux_kernel, enterprise_linux, debian_linux | An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel.

| CVE-2026-35092 | 7.5 high | 1.0% | corosync, redhat, openshift, enterprise_linux | A flaw was found in Corosync. An integer overflow vulnerability in Corosync's join message sanity validation allows a remote, unauthenticated attacker to send crafted User Datagram Protocol (UDP) packets. This can cause the service to crash, leading to a denial of service. This vulnerability specifically affects Corosync deployments configured to use totemudp/totemudpu mode. | Mon 26 Oct |
| CVE-2026-4634 | 7.5 high | 1.0% | redhat, build_of_keycloak | A flaw was found in Keycloak. An unauthenticated attacker can exploit this vulnerability by sending a specially crafted POST request with an excessively long scope parameter to the OpenID Connect (OIDC) token endpoint. This leads to high resource consumption and prolonged processing times, ultimately resulting in a Denial of Service (DoS) for the Keycloak server. | Mon 26 Oct |
| CVE-2026-1584 | 7.5 high | 1.0% | gnu, redhat, gnutls, hardened_images | A flaw was found in gnutls. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted ClientHello message with an invalid Pre-Shared Key (PSK) binder value during the TLS handshake. This can lead to a NULL pointer dereference, causing the server to crash and resulting in a remote Denial of Service (DoS) condition. | Mon 26 Oct |
| CVE-2026-6732 | 7.5 high | 1.0% | xmlsoft, redhat, libxml2, hardened_images, jboss_core_services | A flaw was found in libxml2. This vulnerability occurs when the library processes a specially crafted XML Schema Definition (XSD) validated document that includes an internal entity reference. An attacker could exploit this by providing a malicious document, leading to a type confusion error that causes the application to crash. This results in a denial of service (DoS), making the affected system or application unavailable. | Mon 26 Oct |
| CVE-2026-42009 | 7.5 high | 1.0% | gnu, redhat, gnutls, hardened_images, openshift_container_platform | A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined behavior, resulting in a denial of service. | Mon 26 Oct |
| CVE-2026-7307 | 7.5 high | 1.0% | redhat, build_of_keycloak | A flaw was found in Keycloak. A remote, unauthenticated attacker can send a specially crafted XML input to the Security Assertion Markup Language (SAML) endpoint. This malicious input can cause high CPU usage and worker thread starvation, leading to a Denial of Service (DoS) where the server becomes unavailable. | Mon 26 Oct |
| CVE-2026-7507 | 7.5 high | 1.0% | redhat, build_of_keycloak | A session fixation vulnerability was found in Keycloak's login-actions endpoints. An unauthenticated attacker could exploit this flaw by pre-creating an authentication session and tricking a victim into visiting a maliciously crafted link. By leveraging the /login-actions/restart endpoint—which processes session handles without adequate CSRF protection or cookie ownership validation—an attacker can reset the authentication flow state. This causes Single Sign-On (SSO) to authenticate the victim transparently upon clicking the link, allowing the attacker to hijack the required-action form without needing the victim's credentials. A successful exploit could lead to complete account takeover, including highly privileged administrative accounts. | Mon 26 Oct |
| CVE-2026-47774 | 7.5 high | 1.0% | envoyproxy, redhat, envoy, openshift_service_mesh | Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to versions 1.35.11, 1.36.7, 1.37.3, and 1.38.1, a vulnerability in Envoy's HTTP/2 downstream request processing allows an unauthenticated remote client to trigger excessive memory consumption, potentially resulting in OOM termination of the Envoy process and denial of service. The issue arises from the combination of two behaviors. First, cookie header bytes are not fully accounted for during request header size validation in Envoy. Second, HPACK header block limits in oghttp2/quiche are enforced on encoded bytes without a corresponding limit on total decoded header size. Together, these behaviors allow a malicious client to cause large decoded header allocations while bypassing the intended request header size protections. Versions 1.35.11, 1.36.7, 1.37.3, and 1.38.1 contain a fix. No complete workaround is known short of applying a fix. Possible temporary mitigations include disabling downstream HTTP/2 where operationally feasible; enforcing stricter request header and cookie limits before traffic reaches Envoy; and monitoring Envoy memory usage for abnormal growth under HTTP/2 traffic. | Mon 26 Oct |
| CVE-2026-58015 | 7.5 high | 1.0% | gnome, redhat, glib, enterprise_linux | A flaw was found in GLib. The D-Bus client-side implementation of the DBUS_COOKIE_SHA1 SASL authentication mechanism does not validate the cookie_context parameter received from the server. A malicious D-Bus server can supply a cookie_context containing path traversal sequences, causing the client to read an arbitrary file and exfiltrate sensitive data by verifying guessed file contents against a generated hash. | 22 Oct |
| CVE-2026-19654 | 7.5 high | 1.0% | rsyslog, redhat, enterprise_linux | A unauthenticated remote peer may lead rsyslogd to crash due to a flaw in the optional imptcp module. A crafted input sequence during oversize-frame recovery can cause an invalid internal message length and terminate rsyslogd. No confidentiality or integrity impact, privilege escalation, or code execution has been identified. imtcp and the default imptcp framing modes are not affected. | 21 Oct |
| CVE-2023-50781 | 7.5 high | 1.0% | redhat, m2crypto_project, enterprise_linux, update_infrastructure, m2crypto | A flaw was found in m2crypto. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data. | 15 Oct |
| CVE-2026-5121 | 7.5 high | 1.0% | libarchive, redhat, hardened_images, openshift_container_platform | A flaw was found in libarchive. On 32-bit systems, an integer overflow vulnerability exists in the zisofs block pointer allocation logic. A remote attacker can exploit this by providing a specially crafted ISO9660 image, which can lead to a heap buffer overflow. This could potentially allow for arbitrary code execution on the affected system. | 14 Oct |
| CVE-2026-4424 | 7.5 high | 1.0% | libarchive, redhat, hardened_images, openshift_container_platform | A flaw was found in libarchive. This heap out-of-bounds read vulnerability exists in the RAR archive processing logic due to improper validation of the LZSS sliding window size after transitions between compression methods. A remote attacker can exploit this by providing a specially crafted RAR archive, leading to the disclosure of sensitive heap memory information without requiring authentication or user interaction. | 14 Oct |
| CVE-2026-2100 | 7.5 high | 1.0% | p11-kit_project, redhat, p11-kit, hardened_images, enterprise_linux | A flaw was found in p11-kit. A remote attacker could exploit this vulnerability by calling the C_DeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL. This could lead to the RPC-client attempting to return an uninitialized value, potentially resulting in a NULL dereference or undefined behavior. This issue may cause an application level denial of service or other unpredictable system states. | 14 Oct |
| CVE-2025-6021 | 7.5 high | 1.0% | xmlsoft, redhat, libxml2, jboss_core_services, openshift_container_platform | A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow.

| CVE-2025-7424 | 7.5 high | 1.0% | xmlsoft, redhat, libxslt, openshift_container_platform, enterprise_linux | A flaw was found in the libxslt library. The same memory field, psvi, is used for both stylesheet and input data, which can lead to type confusion during XML transformations. This vulnerability allows an attacker to crash the application or corrupt memory. In some cases, it may lead to denial of service or unexpected behavior. | 12 Oct |
| CVE-2026-15722 | 7.5 high | 1.0% | redhat, directory_server, 389_directory_server, enterprise_linux | A stack buffer overflow flaw was found in 389 Directory Server (389-ds-base). The get_ruvelement_from_berval() function in repl5_ruv.c copies digit characters from a network-supplied RUV berval into a fixed 16-byte stack buffer without bounds checking. A remote unauthenticated attacker can crash the LDAP server by sending a crafted StartNSDS50ReplicationRequest extended operation containing a replica ID field with more than 16 digit characters. The overflow occurs during payload decoding, before any authorization check. Stack protectors limit impact to denial of service. | 8 Oct |
| CVE-2026-11788 | 7.5 high | 1.0% | redhat, directory_server, 389_directory_server, enterprise_linux | A flaw was found in 389 Directory Server. The dereference control plugin does not check for allocation failure before using a BER structure, allowing an unauthenticated remote attacker to crash the LDAP server when the system is under memory pressure. | 8 Oct |
| CVE-2026-11770 | 7.5 high | 1.0% | redhat, directory_server, 389_directory_server, enterprise_linux | A flaw was found in 389 Directory Server. An unauthenticated remote attacker can inject LDAP search filters into the CleanAllRUV replication status-check extended operation. Because the handler performs the search against cn=config with elevated replication plugin privileges and returns a boolean match result, the attacker can extract sensitive server configuration metadata, including replication bind DNs and password storage scheme information. | 8 Oct |
| CVE-2026-3833 | 7.4 high | 1.0% | gnu, redhat, gnutls, hardened_images, openshift_container_platform | A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure. | Mon 26 Oct |
| CVE-2023-0361 | 7.4 high | 1.0% | gnu, redhat, gnutls, enterprise_linux, debian_linux | A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to send a large amount of specially crafted messages to the vulnerable server. By recovering the secret from the ClientKeyExchange message, the attacker would be able to decrypt the application data exchanged over that connection. | 14 Oct |
| CVE-2020-0570 | 7.3 high | 1.0% | qt, redhat, enterprise_linux | Uncontrolled search path in the QT Library before 5.14.0, 5.12.7 and 5.9.10 may allow an authenticated user to potentially enable elevation of privilege via local access. | 8 Oct |
| CVE-2023-6606 | 7.1 high | 1.0% | linux, redhat, linux_kernel, enterprise_linux, enterprise_linux_eus | An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information. | 14 Oct |
| CVE-2023-51767 | 7.0 high | 1.0% | openbsd, fedoraproject, openssh, fedora, enterprise_linux | OpenSSH through 10.0, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges. NOTE: this is disputed by the Supplier, who states "we do not consider it to be the application's responsibility to defend against platform architectural weaknesses." | 15 Oct |
| CVE-2020-1751 | 7.0 high | 1.0% | gnu, redhat, glibc, enterprise_linux, ubuntu_linux | An out-of-bounds write vulnerability was found in glibc before 2.31 when handling signal trampolines on PowerPC. Specifically, the backtrace function did not properly check the array bounds when storing the frame address, resulting in a denial of service or potential code execution. The highest threat from this vulnerability is to system availability. | 14 Oct |
| CVE-2026-39979 | 6.9 medium | 1.0% | jqlang, redhat, jq, ai_inference_server, ansible_automation_platform | jq is a command-line JSON processor. In commits before 2f09060afab23fe9390cce7cb860b10416e1bf5f, the jv_parse_sized() API in libjq accepts a counted buffer with an explicit length parameter, but its error-handling path formats the input buffer using %s in jv_string_fmt(), which reads until a NUL terminator is found rather than respecting the caller-supplied length. This means that when malformed JSON is passed in a non-NUL-terminated buffer, the error construction logic performs an out-of-bounds read past the end of the buffer. The vulnerability is reachable by any libjq consumer calling jv_parse_sized() with untrusted input, and depending on memory layout, can result in memory disclosure or process termination. The issue has been patched in commit 2f09060afab23fe9390cce7cb860b10416e1bf5f. | Mon 26 Oct |
| CVE-2026-44172 | 6.9 medium | 1.0% | mariadb, redhat, enterprise_linux | MariaDB server is a community developed fork of MySQL server. In versions 3.3.18 and 3.4.8, an application that was taking non-validated user input, escaping it with mysql_real_escape_string() and sending it to the database using text protocol and big5 character set was vulnerable to SQL injections, even though mysql_real_escape_string() was supposed to prevent them. This issue has been patched in versions 3.3.19 and 3.4.9. | Mon 26 Oct |
| CVE-2026-71475 | 6.8 medium | 1.0% | redhat, advanced_cluster_management_for_kubernetes, insights-client | A flaw was found in insights-client. A compromised managed cluster, referred to as a 'spoke', can inject unencoded data into the Insights API URL path. This occurs because the ClusterID, which is controlled by the spoke, is used directly in the request path without proper validation or URL encoding. This vulnerability allows a malicious spoke to redirect authenticated requests to unintended API endpoints, potentially leading to information disclosure or unauthorized access. | Sat 24 Oct |
| CVE-2026-18382 | 6.8 medium | 1.0% | redhat, cost_management_metrics_operator | A flaw was found in koku-metrics-operator. The operator's CostManagementMetricsConfig custom resource allows a user able to edit the CR to specify an arbitrary OAuth token endpoint. When authentication.type is set to service-account, the operator sends the tenant's Red Hat SSO client_id and client_secret to this user-controlled URL, allowing the attacker to obtain the credentials. | 23 Oct |
| CVE-2023-4273 | 6.7 medium | 1.0% | linux, fedoraproject, linux_kernel, fedora, enterprise_linux | A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation of the file name reconstruction function, which is responsible for reading file name entries from a directory index and merging file name parts belonging to one file into a single long file name. Since the file name characters are copied into a stack variable, a local privileged attacker could use this flaw to overflow the kernel stack. | 14 Oct |
| CVE-2026-1933 | 6.5 medium | 1.0% | redhat, samba, openshift_container_platform, enterprise_linux | A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-only exports. This could allow modification of SMB-visible file behavior, including converting files into symbolic links or other reparse point types. | Mon 26 Oct |
| CVE-2026-55653 | 6.5 medium | 1.0% | openbsd, redhat, openssh, hardened_images, openshift_container_platform | A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange (DH-GEX) client path. This occurs during FIPS (Federal Information Processing Standards) mode known-group validation when the client processes attacker-controlled DH-GEX group parameters. Successful exploitation leads to client-side process termination, resulting in a Denial of Service (DoS). | Mon 26 Oct |
| CVE-2026-12993 | 6.5 medium | 1.0% | redhat, build_of_apicurio_registry | A flaw was found in Apicurio Registry. The DocumentBuilderAccessor correctly blocks external DTD and schema access but does not disable DOCTYPE declarations or enable FEATURE_SECURE_PROCESSING. An attacker with artifact-write permission can upload XML documents with internal entity-expansion payloads (billion-laughs variant) that cause CPU and heap exhaustion, partially mitigated by the JAXP default 64,000 entity-expansion limit. | Sun 25 Oct |
| CVE-2026-2340 | 6.5 medium | 1.0% | redhat, samba, openshift_container_platform, enterprise_linux | A flaw was found in Samba’s vfs_worm module. The module is intended to provide write-once, read-many (WORM) protections by preventing modification of files after a configurable grace period. Due to insufficient validation during rename operations, an authenticated user with write access to a share could overwrite a protected file by renaming a newly created file over the existing WORM-protected file. | 15 Oct |
| CVE-2025-14512 | 6.5 medium | 1.0% | gnome, redhat, glib, openshift, enterprise_linux | A flaw was found in glib. This vulnerability allows a heap buffer overflow and denial-of-service (DoS) via an integer overflow in GLib's GIO (GLib Input/Output) escape_byte_string() function when processing malicious file or remote filesystem attribute values. | 14 Oct |
| CVE-2023-5981 | 5.9 medium | 1.0% | debian, gnu, debian_linux, gnutls, linux | A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. | 14 Oct |
| CVE-2020-35507 | 5.5 medium | 1.0% | gnu, redhat, binutils, enterprise_linux, hci_compute_node_firmware | There's a flaw in bfd_pef_parse_function_stubs of bfd/pef.c in binutils in versions prior to 2.34 which could allow an attacker who is able to submit a crafted file to be processed by objdump to cause a NULL pointer dereference. The greatest threat of this flaw is to application availability. | 8 Oct |
| CVE-2018-0495 | 4.7 medium | 1.0% | gnupg, canonical, libgcrypt, ubuntu_linux, debian_linux | Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. | 14 Oct |
