CVE-2026-23403

   
Software afectado LINUX KERNEL
 
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.
