CVE-2026-2100

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.

Se encontró una falla en p11-kit. Un atacante remoto podría explotar esta vulnerabilidad al llamar a la función C_DeriveKey en un token remoto con parámetros específicos del mecanismo de derivación IBM kyber o IBM btc establecidos en NULL. Esto podría llevar al cliente RPC intentando devolver un valor no inicializado, resultando potencialmente en una desreferencia NULL o comportamiento indefinido. Este problema puede causar una denegación de servicio a nivel de aplicación o a otros estados impredecibles del sistema.
