    Оригинално описание

    In the Linux kernel, the following vulnerability has been resolved: apparmor: policy_int make sure list heads are initialized before fail path If profile create fails before policy_init is complete the list heads are not properly initialized causing profile_free() sanity checks to trigger the following splat.
