Summary

A vulnerability has been identified in the Linux kernel's wifi (mac80211) module that allows improper operations on non-TDLS stations. The issue arises from the lack of verification whether a station is actually a TDLS station before executing the ENABLE_LINK operation.

Risk Assessment

This vulnerability may lead to unintended side effects, such as modifying channel context and HT protection, potentially impacting network stability and security.

Recommendation

It is recommended to update the Linux kernel to implement the necessary check for TDLS stations before executing the ENABLE_LINK operation.

Original NVD description (English source)

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.
