Technical Description
In the Linux kernel, the following vulnerability has been resolved:
binder: fix UAF in binder_free_transaction()
In binder_free_transaction(), the t->to_proc is read under the t->lock.
However, once the t->lock is dropped, the to_proc can die in parallel.
This leads to a use-after-free error when we attempt to acquire its
inner lock right afterwards:
