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

binder: fix freeze UAF in binder_release_work()

When a binder reference is cleaned up, any freeze work queued in the associated process should also be removed. Otherwise, the reference is freed while its ref->freeze.work is still queued in proc->work leading to a use-after-free issue as shown by the following KASAN report:
