Descriptions

The key_replace_session_keyring function in security/keys/process_keys.c in the Linux kernel before 2.6.39.1 does not initialize a certain structure member, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function, a different vulnerability than CVE-2010-2960.

La función key_replace_session_keyring en security/keys/process_keys.c en el kernel de Linux anterior a v2.6.39.1 no inicializa un determinado miembro de una 'struct', lo que permite a usuarios locales causar una denegación de servicio (puntero a NULL y OOPS) o posiblemente tener un impacto no especificado a través del argumento KEYCTL_SESSION_TO_PARENT a la función keyctl. Se trata de una vulnerabilidad diferente a CVE-2010-2960.
