CVE-2025-71224

Receive-path warnings via missing OCB join check

Published Feb 14, 2026 · Updated Feb 14, 2026

Receive-path state validation in Linux Kernel allows attackers to trigger warnings in the mac80211 OCB path via unspecified vectors. The ieee80211_ocb_rx_no_sta() function continues peer handling without checking ifocb->joined, so it assumes a channel context that does not exist before JOIN_OCB. The flaw is reachable only when RX processing precedes JOIN_OCB on an OCB interface; published sources report RX-path warnings, not a crash or code execution.
