In the Linux kernel, the following vulnerability has been resolved: rust_binder: clear freeze listener on node removal Generally userspace is supposed to explicitly clear freeze listeners before they drop the refcount on the node ref to zero, but there's nothing forcing that. Currently, in this scenario the freeze listener remains in the freeze_listeners rbtree and in the remote node's freeze listener list, even though the ref for which the listener is registered is gone. This could potentially lead to a memory leak due to a refcount cycle. Thus, remove the freeze listener in this scenario.

A flaw was found in the Linux kernel's Rust Binder component. This vulnerability occurs when a freeze listener is not properly cleared upon node removal, leading to a reference count cycle. This can result in a memory leak, potentially impacting system stability and performance over time.
