Description OSIDB Bzimport 2026-05-01 15:01:47 UTC
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.
