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

Thanks,

Paul
