CVE-2025-71224: wifi: mac80211: ocb: skip rx_no_sta when interface is not joined

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: ocb: skip rx_no_sta when interface is not joined ieee80211_ocb_rx_no_sta() assumes a valid channel context, which is only present after JOIN_OCB. RX may run before JOIN_OCB is executed, in which case the OCB interface is not operational. Skip RX peer handling when the interface is not joined to avoid warnings in the RX path.

Security readout for executives and security teams

Plain-English summary

This Linux kernel issue affects a specialized Wi-Fi OCB path. Before an OCB interface has joined a channel context, received traffic can trigger peer-handling code that expects one, causing RX-path warnings. The public record does not state data theft, privilege escalation, or active exploitation.

Executive priority

Treat as a targeted kernel maintenance issue, not an emergency based on current evidence. Prioritize patching for wireless, automotive, roadside, lab, or embedded systems using OCB; handle other Linux assets through normal kernel update cycles.

Technical view

In mac80211 OCB mode, ieee80211_ocb_rx_no_sta() assumed a valid channel context that only exists after JOIN_OCB. RX could occur before JOIN_OCB, when the interface is not operational. The fix skips RX peer handling unless the OCB interface is joined.

Likely exposure

Exposure appears limited to Linux systems using kernels with the affected mac80211 OCB implementation and relevant Wi-Fi hardware or OCB/802.11p workflows. Ordinary servers without this wireless path are unlikely to be exposed, but confirm kernel builds and enabled wireless features.

Exploitation context

The CVE is not listed as KEV, and the source bundle provides no evidence of public exploitation. The documented behavior is RX-path warnings when traffic is processed before OCB join state is established.

Researcher notes

The record gives no CVSS, CWE, exploit details, or impact beyond RX-path warnings. Analysis should focus on whether the affected OCB state transition is reachable in deployed kernels and whether warnings imply operational instability in specific environments.

Mitigation direction

  • Apply vendor-supported Linux kernel updates containing the referenced stable fixes.
  • Check distribution advisories for backported fixed kernel versions.
  • Disable unused OCB wireless functionality where operationally feasible.
  • Prioritize systems with Wi-Fi hardware and OCB/802.11p usage.

Validation and detection

  • Inventory Linux kernel versions on systems with Wi-Fi capabilities.
  • Confirm whether mac80211 OCB functionality is enabled or used.
  • Check vendor kernel changelogs for the referenced stable commits.
  • Review kernel logs for related RX-path warnings.
  • Retest after updating to a fixed vendor kernel.
