  "details": "In the Linux kernel, the following vulnerability has been resolved:  wifi: cfg80211: only group hidden BSSes with beacon entries  When a probe response for an unknown BSS comes in, __cfg80211_bss_update() looks for an existing entry with the same BSSID and a hidden (zero-length or NUL-filled) SSID, and if it finds one it groups them, using the beacon IEs from the existing entry.  But that could find another entry without a beacon, if it was also from a probe response (with SSID), so there's a group without beacon elements.  If a beacon with a hidden SSID for that BSSID arrives later, cfg80211_combine_bsses() goes looking for the probe response entries that belong to it - i.e. entries with the same BSSID and channel that have no beacon IEs - and finds those two. They are already grouped with each other, so it hits its    WARN_ON_ONCE(bss-\u003epub.hidden_beacon_bss)   WARN_ON_ONCE(!list_empty(\u0026bss-\u003ehidden_list))  which are there because an entry without beacon elements is not supposed to be part of a group yet.  Only combine entries when a beacon was already received, ones that are kept separate will be combined when a beacon arrives.",
