An official patch is available and included in Linux kernel updates distributed by Ubuntu and other vendors. Users should apply the latest Linux kernel security updates that include the fix for this issue. The vendor advisory confirms the availability of the fix. No additional mitigation steps are required beyond applying the update.
Description
A vulnerability in the Linux kernel's mac80211 wireless subsystem related to the OCB (Outside Context of a BSS) mode was resolved. The flaw involved the function ieee80211_ocb_rx_no_sta() assuming a valid channel context, which may not be present if the interface is not joined, potentially causing warnings in the receive path. This issue has been fixed by skipping RX peer handling when the interface is not joined. The vulnerability affects certain Linux kernel versions prior to specific patched releases. A patch is available as part of a broader Linux kernel security update.
