CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's AppArmor feature, specifically related to unconfined user namespace restrictions, which can allow a confined task to escape if two transitions through an unconfined profile are executed. This flaw could lead to privilege escalation, compromising system security. Organizations utilizing Linux systems with AppArmor should prioritize addressing this issue to mitigate potential risks.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: apparmor: fix unconfined user namespace restriction forced stack If a task is already confined by a stack the unprivileged transition restriction on unconfined is not correctly, applied. This results in an escape if two transitions through an unconfined profile can be executed. Fix this by pushing the check into the per profile label build. The check will always be done against unconfined and result in a stack of just the unconfined component when necessary.
