Description OSIDB Bzimport 2026-02-14 17:03:33 UTC 
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.
