Detailsinfo

A vulnerability was found in Linux Kernel up to 6.18.9. It has been declared as critical. This vulnerability affects the function ieee80211_ocb_rx_no_sta of the component OCB Interface. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.
