Summary
wifi: mac80211: check tdls flag in ieee80211_tdls_oper
Details

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

wifi: mac80211: check tdls flag in ieee80211tdlsoper

When NL80211TDLSENABLE_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.
