  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: check tdls flag in ieee80211_tdls_oper\n\nWhen NL80211_TDLS_ENABLE_LINK is called, the code only checks if the\nstation exists but not whether it is actually a TDLS station. This\nallows the operation to proceed for non-TDLS stations, causing\nunintended side effects like modifying channel context and HT\nprotection before failing.\n\nAdd a check for sta-\u003esta.tdls early in the ENABLE_LINK case, before\nany side effects occur, to ensure the operation is only allowed for\nactual TDLS peers.",
