Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> apparmor: fix memory leak in verify_header<br /> <br /> The function sets `*ns = NULL` on every call, leaking the namespace<br /> string allocated in previous iterations when multiple profiles are<br /> unpacked. This also breaks namespace consistency checking since *ns<br /> is always NULL when the comparison is made.<br /> <br /> Remove the incorrect assignment.<br /> The caller (aa_unpack) initializes *ns to NULL once before the loop,<br /> which is sufficient.
