Summary
apparmor: fix reference count leak in aa_pivotroot()
Details

In the Linux kernel, the following vulnerability has been resolved:

apparmor: fix reference count leak in aa_pivotroot()

The aapivotroot() function has a reference counting bug in a specific path. When aareplacecurrentlabel() 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.
