CVE-2026-43052 Details
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.
A vulnerability exists in the Linux kernel's mac80211 component, specifically within the ieee80211_tdls_oper function. When the NL80211_TDLS_ENABLE_LINK command is issued, the function only verifies the existence of the station, without confirming if it is a TDLS station. This oversight allows the command to affect non-TDLS stations, leading to unintended consequences such as altering channel context and HT protection, before ultimately failing. The vulnerability has been addressed by adding a check for the TDLS status of the station early in the ENABLE_LINK process, preventing these side effects from occurring on non-TDLS peers.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for downloading the patched version are available on the Linux Kernel Archives.
