CVE-2026-2100

7.5 high SSVC exploitation: none Modified
NVD · CVE.org

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.
