The vulnerability allows a local user to leave deferred work items uncleared, potentially causing resource exhaustion and a denial of service.

The vulnerability exists due to incomplete cleanup in the Linux kernel rust_binder Thread::release() method when a thread exits with deferred work items on its todo list. A local user can cause a thread to exit while it has an active outgoing transaction to leave deferred work items uncanceled, potentially retaining resources and causing a denial of service.
