Riassunto

di MITRE • 28/08/2026

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.
