      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: validate extension-frame layout before RX\n\nExtension frames only have the extension header at the regular 802.11\nheader offset. The generic RX path can still reach helpers and interface\ndispatch code that read regular header address fields before unsupported\nextension subtypes are dropped.\n\nmac80211 currently only handles S1G beacon extension frames. Drop other\nextension subtypes before they can reach regular-header RX processing.\nFor S1G beacons, linearize the SKB with the management-frame path and\nrequire the fixed S1G beacon header, including optional fixed fields\nindicated by frame control, before generic RX dispatch.\n\nRoute S1G beacons through the station/default-link RX path without\nregular-header station lookup. Avoid regular-header address reads in the\nmac80211 RX paths that process S1G extension beacons, including\naccept-frame, duplicate-detection, address-copy, and MLO\naddress-translation paths.\n\nAlso make ieee80211_get_bssid() length-safe before returning the S1G\nsource-address pointer.",
