{"id":"CVE-2026-80722","summary":"wifi: mac80211: validate individual TWT params before driver setup","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: validate individual TWT params before driver setup\n\nieee80211_process_rx_twt_action() only partially validates a received\nS1G TWT setup frame before queueing it.\n\nAn individual agreement can therefore reach ieee80211_s1g_rx_twt_setup()\nwith twt-\u003elength too short for the full struct ieee80211_twt_params.\n\nThe individual path passes twt to drv_add_twt_setup(). Both the tracepoint\nand the driver callback consume the complete parameters block, not merely\nreq_type. Do not pass a short individual agreement to the driver.\nBroadcast agreements remain unchanged because they are rejected locally\nafter accessing only req_type.\n\n[edit commit message to not overclaim lack of validation nor\n understate driver impact]","modified":"2026-08-31T03:30:34.360841241Z","published":"2026-08-28T06:53:17.886Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80722.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0502d5077e419427d80f4d46ba95d0067f5fb916"},{"type":"WEB","url":"https://git.kernel.org/stable/c/09d60d1f72e6598241490eb6c4e97245af895c09"},{"type":"WEB","url":"https://git.kernel.org/stable/c/47fb04c3826e1f90271d405523043d6708b9072a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/92fcd0f30dc8e51f252589b082d46851d295cc1a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ade9e2f0f7f4d3089600ac2af8ef0b91746f923b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b558e07708d886acfcf4b0391ed7a8546e81d326"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ff558072d199c1d641d1561da622e67f780514de"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80722.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80722"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f5a4c24e689f54e66201f04d343bdd2e8a1d7923"},{"fixed":"92fcd0f30dc8e51f252589b082d46851d295cc1a"},{"fixed":"09d60d1f72e6598241490eb6c4e97245af895c09"},{"fixed":"ff558072d199c1d641d1561da622e67f780514de"},{"fixed":"ade9e2f0f7f4d3089600ac2af8ef0b91746f923b"},{"fixed":"b558e07708d886acfcf4b0391ed7a8546e81d326"},{"fixed":"47fb04c3826e1f90271d405523043d6708b9072a"},{"fixed":"0502d5077e419427d80f4d46ba95d0067f5fb916"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80722.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.15.0"},{"fixed":"5.15.216"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.183"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.151"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.103"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.44"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80722.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
