Vulnerability from github – Published: 2026-05-01 15:30 – Updated: 2026-05-07 18:30

Details

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

wifi: mac80211: check tdls flag in ieee80211_tdls_oper

When NL80211_TDLS_ENABLE_LINK is called, the code only checks if the station exists but not whether it is actually a TDLS station. This allows the operation to proceed for non-TDLS stations, causing unintended side effects like modifying channel context and HT protection before failing.

Add a check for sta->sta.tdls early in the ENABLE_LINK case, before any side effects occur, to ensure the operation is only allowed for actual TDLS peers.

Severity ?

7.1 (High)
