CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's rust_binder component, where freeze listeners are not properly cleared upon node removal, potentially leading to memory leaks due to reference count cycles. This issue could impact system stability and resource management, making it critical for developers and system administrators using affected Linux distributions to prioritize remediation. Users should ensure their systems are updated to mitigate the risks associated with this vulnerability.
Original NVD Description
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.
