Doc Text:	A flaw was found in the Linux kernel's mac80211 wireless subsystem. The Tunneled Direct Link Setup (TDLS) code fails to verify whether a station is a direct-link peer rather than an access point before executing TDLS operations. A local attacker can exploit this flaw to cause inconsistent kernel state and warnings, potentially resulting in a Denial of Service (DoS) when the access point station is removed.	Story Points:	---

Description OSIDB Bzimport 2026-10-06 09:42:02 UTC

In the Linux kernel, the following vulnerability has been resolved:

wifi: mac80211: only operate on TDLS peers in the TDLS code

ieee80211_tdls_oper() can operate on the AP station, which then
yields various warnings when the AP station is removed then or
at a later point in time after being confused for a TDLS peer.

Always check that the station is a TDLS peer.
