Hello,

with v6.12 we encountered a kernel BUG (panic on our systems) that is caused by a NULL pointer dereference inside the apparmor's profile_transition code. I've contacted John Johansen as the maintainer for the apparmor system, and he pointed me to 17d0d04f3c99 as a fix for that issue. That commit has now landed in v6.13, would it be possible to backport this to v6.12? Commit is

17d0d04f3c99 apparmor: allocate xmatch for nullpdb inside aa_alloc_null

Now queued up, thanks.
