This also keeps\nmac_work from running over an already suspended HIF, which the previous\nsplit (async cancel under the lock, sync cancel after release) would\nhave allowed.","state":0,"publishedAt":"2026-09-11T19:42:11.588+00:00","modifiedAt":"2026-10-19T08:45:22.189+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"unaffected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/net/wireless/mediatek/mt76/mt7615/main.c\"\n ],\n \"versions\": [\n {\n \"version\": \"c6bf20109a3fae92402cb76ad709ec5256bcd169\",\n \"lessThan\": \"36c73b86a09f0e51c0f81a75c8945b6c5557ff27\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"c6bf20109a3fae92402cb76ad709ec5256bcd169\",\n \"lessThan\": \"33d29aeb4c0eede92622a7d04ea492b94c30f089\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"c6bf20109a3fae92402cb76ad709ec5256bcd169\",\n \"lessThan\": \"ef2ec8b537c3a54e241d693bd03016f80d0d4484\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"c6bf20109a3fae92402cb76ad709ec5256bcd169\",\n \"lessThan\": \"3114d479f2a1d31b2e6214c395794c6e5715e579\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"c6bf20109a3fae92402cb76ad709ec5256bcd169\",\n \"lessThan\": \"4506e229b2e468b8c64bcf52c50c41a3bf2e633e\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"c6bf20109a3fae92402cb76ad709ec5256bcd169\",\n \"lessThan\": \"44be85af3e1772ffb3332feafedad2a73b22854c\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"c6bf20109a3fae92402cb76ad709ec5256bcd169\",\n \"lessThan\": \"bda8324270b1ac91bfba1df8928e0570e29759e8\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n }\n ]\n }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"affected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/net/wireless/mediatek/mt76/mt7615/main.c\"\n ],\n \"versions\": [\n {\n \"version\": \"5.8\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"5.8\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.221\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.188\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.157\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.109\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.50\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.2.4\",\n \"lessThanOrEqual\": \"7.2.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.3\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/36c73b86a09f0e51c0f81a75c8945b6c5557ff27","https://git.kernel.org/stable/c/33d29aeb4c0eede92622a7d04ea492b94c30f089","https://git.kernel.org/stable/c/ef2ec8b537c3a54e241d693bd03016f80d0d4484","https://git.kernel.org/stable/c/3114d479f2a1d31b2e6214c395794c6e5715e579","https://git.kernel.org/stable/c/4506e229b2e468b8c64bcf52c50c41a3bf2e633e","https://git.kernel.org/stable/c/44be85af3e1772ffb3332feafedad2a73b22854c","https://git.kernel.org/stable/c/bda8324270b1ac91bfba1df8928e0570e29759e8"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-80938","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-80938","identifiers":["CVE-2026-80938"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
