Description

In the Linux kernel the following vulnerability has been resolved:

apparmor: fix reference count leak in aa_pivotroot()

The aa_pivotroot() function has a reference counting bug in a specific path. When aa_replace_current_label() returns on success the function forgets to decrement the reference count of “target” which is increased earlier by build_pivotroot() causing a reference leak.

Fix it by decreasing the refcount of “target” in that path.
