In the Linux kernel, the following vulnerability has been resolved:
apparmor: fix potential UAF in aa_replace_profiles
The function aa_replace_profiles was accessing udata->size after calling
aa_put_loaddata(udata), causing a potential UAF.
Fixed this by saving the size to a local variable before dropping the
reference.
