Summary
CVE-2026-23403 affecting package kernel for versions less than 6.6.130.1-1
Details

In the Linux kernel, the following vulnerability has been resolved:

apparmor: fix memory leak in verify_header

The function sets *ns = NULL on every call, leaking the namespace string allocated in previous iterations when multiple profiles are unpacked. This also breaks namespace consistency checking since *ns is always NULL when the comparison is made.

Remove the incorrect assignment. The caller (aa_unpack) initializes *ns to NULL once before the loop, which is sufficient.
