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.
