Descriptions

The keyctl_session_to_parent function in security/keys/keyctl.c in the Linux kernel 2.6.35.4 and earlier expects that a certain parent session keyring exists, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function.

La función keyctl_session_to_parent en security/keys/keyctl.c en el kernel de Linux v2.6.35.4 y anteriores, espera que determinados keyrings de sesión aparezcan, lo que permite a usuarios locales provocar una denegación de servicio(deferencia a puntero nulo y caída de sistema) o posiblemente tener otro impacto sin especificar a través del argumento KEYCTL_SESSION_TO_PARENT a la función keyctl.
