CVE-2026-90246

AppArmor in the Linux kernel contains an integer overflow in the verify_tags() bounds check during policy blob validation. The 32-bit addition i + cnt wraps when an attacker-supplied count is near U32_MAX , bypassing the guard and causing an out-of-bounds read past a kcalloc allocation in the set...

CVE-2026-90231

CVE-2026-90231 is a flaw in the Linux kernel's AppArmor subsystem. When a task is already confined by a profile stack , the unprivileged user-namespace transition restriction on the unconfined profile is not correctly enforced. This allows a confinement escape if two transitions through an unconf...

CVE-2026-90179

AppArmor in the Linux kernel is affected by a deadlock triggered when a process uses change_hat in complain mode and the target hat does not exist. The root cause is a lock-ordering conflict : change_hat() holds a lock while searching the hat list, but aa_new_learning_profile() attempts to acquir...
