CVE-2025-68260

Kernel crash via Rust Binder death-list race

Published Dec 16, 2025 · Updated Dec 16, 2025

Race condition in Linux 6.18 Rust Binder allows local users to crash the kernel through concurrent death-notification operations. The Node::release path moves death-list entries to an unlocked local list while unsafe removal concurrently mutates the same prev/next pointers, corrupting list memory. Exploitation requires the Rust Binder driver and a race during node release; the demonstrated consequence is a kernel paging fault and crash.
