CVE-2026-64466

CVE-2026-64466 affects the Linux kernel where, in the rust_binder component, a freeze listener may linger in the freeze_listeners red-black tree and the remote node’s listener list after the referenced object’s refcount reaches zero. This can create a refcount cycle and potentially a memory leak....
