| CVE | CVSS | EPSS | Vendor, product | Description | Modified |
|---|---|---|---|---|---|
| CVE-2026-14474 | 8.8 high | 1.0% | no CPE yet | A flaw was found in SSSD's LDAP sudo provider. When the ldap_sudo_search_base option is not explicitly configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker with write access to any subtree can inject a sudoRole object granting root-level sudo privileges on all SSSD-enrolled hosts. | 8 Oct |
| CVE-2026-14476 | 8.0 high | 1.0% | no CPE yet | A path traversal flaw was found in SSSD's AD GPO provider. The ad_gpo_extract_smb_components() function does not sanitize .. sequences in the gPCFileSysPath LDAP attribute, allowing an attacker with AD GPO management access to write files outside the GPO cache directory as root. On default RHEL configurations with SELinux enforcing, this can be used to inject Kerberos configuration leading to authentication bypass. | 8 Oct |
| CVE-2026-104048 | 8.1 high | 0.00% | fedoraproject, redhat, sssd, openshift_container_platform, enterprise_linux | A flaw was found in SSSD. In trust-enabled identity management environments, SSSD evaluates Host-Based Access Control (HBAC) rules by stripping domain qualifiers and comparing only short usernames. An authenticated user in a trusted domain who shares the same username as an authorized local account can bypass access policies and gain unauthorized access to protected services or hosts. | 9 Oct |
| CVE-2026-87853 | 7.5 high | 0.00% | no CPE yet | A flaw was found in SSSD's IdP authentication provider. The eval_access_token_buf() function compares the OIDC subject identifier using strncmp() with the authenticated user's identifier length, performing a prefix comparison instead of an exact match. An attacker whose IdP identifier is a strict prefix of a target user's identifier can authenticate as the target user. | 21 Oct |
| CVE-2026-104046 | 6.2 medium | 0.00% | fedoraproject, redhat, sssd, openshift_container_platform, enterprise_linux | A flaw was found in SSSD (System Security Services Daemon). When Identity Provider (IdP) authentication is enabled, pre-authentication requests retain state in memory without being cleared or timed out. A local attacker can repeatedly initiate authentication flows without completing them, causing unbounded memory consumption. This memory exhaustion can lead to a Denial of Service (DoS) by degrading or terminating SSSD authentication services. | 13 Oct |
| CVE-2026-104044 | 6.2 medium | 0.00% | no CPE yet | A flaw was found in sssd. A local attacker can trigger a Denial of Service (DoS) by sending a specially crafted Pluggable Authentication Module (PAM) request when passkey authentication is enabled. Due to a missing state validation check in passkey Kerberos handling, the PAM responder dereferences an uninitialized pointer and crashes. This failure disrupts authentication services on the host. | 8 Oct |
| CVE-2026-104040 | 6.1 medium | 0.00% | fedoraproject, redhat, sssd, openshift_container_platform, enterprise_linux | A flaw was found in SSSD. When configured with the Entra ID identity provider, input lookup names containing single quotes are not properly escaped before being included in Microsoft Graph Open Data Protocol (OData) queries. A low-privileged local user can exploit this flaw by submitting a crafted search request, altering query filters to broaden user or group searches. This can lead to information disclosure by retrieving unintended directory objects, as well as a Denial of Service (DoS) through excessive processing and cache population. | 16 Oct |
| CVE-2026-104029 | 5.5 medium | 0.00% | fedoraproject, redhat, sssd, openshift_container_platform, enterprise_linux | A flaw was found in SSSD. A local attacker can exploit this vulnerability by sending a specially crafted request to the autofs responder UNIX socket. Due to improper buffer offset calculation during request parsing, the service performs an out-of-bounds memory read. This flaw can cause the autofs responder process to crash, resulting in a denial of service (DoS). | 13 h ago |
| CVE-2026-104030 | 5.5 medium | 0.00% | fedoraproject, redhat, sssd, openshift_container_platform, enterprise_linux | A flaw was found in sssd. This vulnerability allows a local user to cause a Denial of Service (DoS) by submitting a specially crafted passkey authentication token that lacks null terminators. The authentication service reads past the end of the provided memory buffer, causing the process to crash and disrupting authentication services. | 13 h ago |
| CVE-2026-104031 | 5.5 medium | 0.00% | fedoraproject, redhat, sssd, openshift_container_platform, enterprise_linux | A flaw was found in SSSD. In configurations where the autofs responder service is enabled, memory allocated during successful request processing is not released until the client connection terminates. A local attacker can exploit this vulnerability by maintaining an open connection and repeatedly submitting valid requests, leading to memory exhaustion and a Denial of Service (DoS). | 13 h ago |
| CVE-2026-104032 | 5.5 medium | 0.00% | fedoraproject, redhat, sssd, openshift_container_platform, enterprise_linux | A flaw was found in SSSD. An unprivileged local user can repeatedly request master automount map updates through the autofs responder due to missing authorization checks. This triggers global cache invalidation and forces repeated lookups to backend directory providers, leading to a Denial of Service (DoS) from degraded automount availability and elevated resource consumption. | 13 h ago |
| CVE-2026-6245 | 5.5 medium | 0.00% | fedoraproject, redhat, sssd, openshift_container_platform, enterprise_linux | A flaw was found in the System Security Services Daemon (SSSD). The pam_passkey_child_read_data() function within the PAM passkey responder fails to properly handle raw bytes received from a pipe. Because the data is treated as a NUL-terminated C string without explicit termination, it results in an out-of-bounds read when processed by functions like snprintf(). A local attacker could potentially trigger this vulnerability by initiating a crafted passkey authentication request, causing the SSSD PAM responder to crash, resulting in a local Denial of Service (DoS). | Mon 26 Oct |
| CVE-2026-88252 | 5.5 medium | 0.00% | fedoraproject, redhat, sssd, openshift_container_platform, enterprise_linux | A flaw was found in sssd. A local user can cause a Denial of Service (DoS) by exhausting the responder service's available file descriptors (system handles used for open connections). By opening and maintaining many concurrent connections to a responder socket while continuing to queue new connection attempts, an attacker can trigger an unthrottled retry loop. This condition leads to high CPU utilization and stalls the service, preventing legitimate identity and authentication requests from being processed. | 20 Oct |
| CVE-2026-90995 | 5.5 medium | 0.00% | fedoraproject, redhat, sssd, openshift_container_platform, enterprise_linux | A flaw was found in SSSD (System Security Services Daemon). A local attacker with privileges to connect to the PAM (Pluggable Authentication Modules) responder socket can send a specially crafted protocol request. If the `pam_app_services` configuration is enabled and the service item is omitted from the request, a NULL pointer dereference can occur. This vulnerability leads to a denial of service, causing the PAM responder to crash and disrupt authentication services. | 14 Oct |
| CVE-2026-104035 | 5.5 medium | 0.00% | no CPE yet | A flaw was found in SSSD. An issue in the Kerberos Credential Manager (KCM) responder allows a local user to cause a Denial of Service (DoS) by maintaining a persistent connection and repeatedly storing and destroying credentials. Because the service fails to release cached objects from memory when credentials are removed, memory consumption grows continuously, ultimately exhausting available memory and rendering the service unresponsive. | 8 Oct |
| CVE-2026-104047 | 5.3 medium | 0.00% | fedoraproject, redhat, sssd, openshift_container_platform, enterprise_linux | A flaw was found in SSSD. When configured to use Microsoft Entra ID, search inputs are not properly sanitized before being incorporated into directory query filters. A local user can exploit this vulnerability by submitting a crafted lookup request, manipulating the query logic to cause unauthorized information disclosure from the directory. | 9 Oct |
| CVE-2026-104045 | 4.7 medium | 0.00% | fedoraproject, redhat, sssd, openshift_container_platform, enterprise_linux | A flaw was found in SSSD. A local user can trigger a Denial of Service (DoS) by exploiting a race condition in the autofs responder between asynchronous enumeration completion and map invalidation. By repeatedly sending concurrent map enumeration and invalidation requests, an attacker can cause memory to leak, leading to excessive memory consumption that can disrupt or crash the autofs service. | 13 Oct |
| CVE-2026-104039 | 4.7 medium | 0.00% | no CPE yet | A flaw was found in SSSD. A local user can cause a denial of service (DoS) by disrupting system authentication services. When handling Generic Security Services Application Programming Interface (GSSAPI) authentication in the Pluggable Authentication Module (PAM) responder, cached connection state is freed upon completion without clearing the reference pointer. An attacker can exploit this by sending an additional request over the same connection, causing the service to access invalid memory and unexpectedly terminate. | 8 Oct |
