En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:

drm/virtio: Corrige un error de NULL frente a ERR_PTR() en virtio_gpu_user_framebuffer_create()

Smatch advierte de que devolver un NULL aquí provocará una desreferencia de puntero NULL en drm_mode_addfb2(). Devuelve en su lugar un puntero de error.
