AI-suggested
A fix for this vulnerability has been implemented in the linux-azure kernel versions listed as affected. Users should update to patched versions of the linux-azure kernel to remediate this issue. Patch status beyond the affected versions is not explicitly stated; check vendor advisories for the latest updates.
Description
A vulnerability in the Linux kernel's AppArmor security module was resolved that involved improper initialization of list heads when profile creation fails before policy initialization completes. This flaw could cause sanity checks in profile freeing to trigger a kernel warning and potentially a kernel crash (splat). The issue affects specific versions of the linux-azure kernel and was addressed to ensure list heads are properly initialized before failure paths are taken.
