GHSA-6HCF-6997-PQ7Q
Vulnerability from github – Published: 2026-10-14 15:32 – Updated: 2026-10-14 15:32In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: require a peer station for TDLS setup confirm
It's nonsense for the setup confirm to go to station that doesn't even exist, and it hits a warning when building the frame:
WARN_ON_ONCE(!sta || !ap_sta)
Only accept WLAN_TDLS_SETUP_CONFIRM when the station is already there as a TDLS station. Need to copy the call to ieee80211_tdls_prep_mgmt_packet() since the existing WLAN_TDLS_DISCOVERY_REQUEST already falls through to it.
