Severity ?
8.8 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: validate individual TWT params before driver setup ieee80211_process_rx_twt_action() only partially validates a received S1G TWT setup frame before queueing it. An individual agreement can therefore reach ieee80211_s1g_rx_twt_setup() with twt->length too short for the full struct ieee80211_twt_params. The individual path passes twt to drv_add_twt_setup(). Both the tracepoint and the driver callback consume the complete parameters block, not merely req_type. Do not pass a short individual agreement to the driver. Broadcast agreements remain unchanged because they are rejected locally after accessing only req_type. [edit commit message to not overclaim lack of validation nor understate driver impact]

an adjacent attacker within radio range sends crafted 802.11 management frames to a vulnerable AP.\\nAC:L - The attacker fully controls the TWT element length and payload; ieee80211_process_rx_twt_action() only validates two bytes of req_type before queueing, so a short individual agreement reliably reaches drv_add_twt_setup() without races or victim-specific timing.\\nPR:N - No Linux privileges on the victim AP are required; exploitation needs only normal 802.11 association as a WiFi client to an S1G AP with twt_responder enabled and a driver implementing add_twt_setup (e.g. MediaTek mt7915/mt7996).\\nUI:N - No deliberate victim action is needed beyond operating an S1G AP that accepts associated stations; the attacker directly injects the malformed TWT setup frame and mac80211 processes it automatically on receive.\\nS:U - Impact is kernel/driver heap memory corruption on the AP host within the same security authority; it does not cross VM, IOMMU, or sandbox boundaries (standard kernel compromise scope).\\nC:H - drv_add_twt_setup(), its tracepoint, and driver callbacks read the full ieee80211_twt_params (twt, min_twt_dur, mantissa, channel) beyond the validated skb bounds, causing out-of-bounds reads of adjacent skb/heap memory that can disclose kernel data.\\nI:H - MediaTek add_twt_setup() handlers write twt_agrt fields (req_type, min_twt_dur, twt) past the undersized params block into skb tail/heap memory, providing out-of-bounds write primitives exploitable for further memory corruption or code execution.\\nA:H - Out-of-bounds access in mac80211/driver TWT setup can kernel-oops the AP or hang/crash WiFi firmware when corrupted parameters are programmed into hardware TWT state from attacker-controlled short frames.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"f5a4c24e689f54e66201f04d343bdd2e8a1d7923\", \"lessThan\": \"92fcd0f30dc8e51f252589b082d46851d295cc1a\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f5a4c24e689f54e66201f04d343bdd2e8a1d7923\", \"lessThan\": \"09d60d1f72e6598241490eb6c4e97245af895c09\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f5a4c24e689f54e66201f04d343bdd2e8a1d7923\", \"lessThan\": \"ff558072d199c1d641d1561da622e67f780514de\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f5a4c24e689f54e66201f04d343bdd2e8a1d7923\", \"lessThan\": \"ade9e2f0f7f4d3089600ac2af8ef0b91746f923b\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f5a4c24e689f54e66201f04d343bdd2e8a1d7923\", \"lessThan\": \"b558e07708d886acfcf4b0391ed7a8546e81d326\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f5a4c24e689f54e66201f04d343bdd2e8a1d7923\", \"lessThan\": \"47fb04c3826e1f90271d405523043d6708b9072a\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f5a4c24e689f54e66201f04d343bdd2e8a1d7923\", \"lessThan\": \"0502d5077e419427d80f4d46ba95d0067f5fb916\", \"versionType\": \"git\"}], \"programFiles\": [\"net/mac80211/s1g.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.15\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.15\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.15.216\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.183\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.151\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.103\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.44\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.8\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/mac80211/s1g.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/92fcd0f30dc8e51f252589b082d46851d295cc1a\"}, {\"url\": \"https://git.kernel.org/stable/c/09d60d1f72e6598241490eb6c4e97245af895c09\"}, {\"url\": \"https://git.kernel.org/stable/c/ff558072d199c1d641d1561da622e67f780514de\"}, {\"url\": \"https://git.kernel.org/stable/c/ade9e2f0f7f4d3089600ac2af8ef0b91746f923b\"}, {\"url\": \"https://git.kernel.org/stable/c/b558e07708d886acfcf4b0391ed7a8546e81d326\"}, {\"url\": \"https://git.kernel.org/stable/c/47fb04c3826e1f90271d405523043d6708b9072a\"}, {\"url\": \"https://git.kernel.org/stable/c/0502d5077e419427d80f4d46ba95d0067f5fb916\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"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().
