CVE-2026-23403
Description
AI Translation Available
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.
