CVE-2026-43052
Vulnerability Description
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.
