A vulnerability in the Linux kernel's network bridge code involving CFM and MRP frame handlers has been resolved. The issue arises because CFM and MRP register a global frame type node that is linked into multiple bridge lists, causing list corruption when unregistered on one bridge. This affects uncommon protocol handlers that can only be installed once per bridge. The fix involves tracking per-bridge enable state with option bits and removing the shared list structure, improving both correctness and performance.
