In the Linux kernel, the following vulnerability has been resolved:
binder: fix memleak of proc->delivered_freeze
If a freeze notification is cleared with BCCLEARFREEZENOTIFICATION before calling binderfreezenotificationdone(), then it is detached from its reference (e.g. ref->freeze) but the work remains queued in proc->deliveredfreeze. This leads to a memory leak when the process exits as any pending entries in proc->deliveredfreeze are not freed:

This patch fixes the leak by ensuring that any pending entries in proc->deliveredfreeze are freed during binderdeferred_release().
