wifi: mac80211: check tdls flag in ieee80211_tdls_oper

Type: advisorySource: Official CVE List1 source record

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.
