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.
