Описание
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.
