# Linux kernel: Rust Binder leaves deferred work items uncleaned on thread exit

In the Rust Binder driver, deferred work items on a thread's todo list are not cleaned up when the thread exits, which can happen if the thread dies during an outgoing transaction. The sources describe a resource-cleanup flaw and do not state what an attacker gains from it.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

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

rust_binder: cancel deferred work items in thread exit

If there are deferred work items on the thread todo list, then they are
not cleaned up in the Thread::release() method. Thus, update the code to
clean up the work items even if they are deferred.

This can happen if the thread dies while it has an active outgoing
transaction.
