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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wireless/mediatek/mt76/mt7615/main.c"],"versions":[{"version":"c6bf20109a3fae92402cb76ad709ec5256bcd169","lessThan":"36c73b86a09f0e51c0f81a75c8945b6c5557ff27","status":"affected","versionType":"git"},{"version":"c6bf20109a3fae92402cb76ad709ec5256bcd169","lessThan":"33d29aeb4c0eede92622a7d04ea492b94c30f089","status":"affected","versionType":"git"},{"version":"c6bf20109a3fae92402cb76ad709ec5256bcd169","lessThan":"ef2ec8b537c3a54e241d693bd03016f80d0d4484","status":"affected","versionType":"git"},{"version":"c6bf20109a3fae92402cb76ad709ec5256bcd169","lessThan":"3114d479f2a1d31b2e6214c395794c6e5715e579","status":"affected","versionType":"git"},{"version":"c6bf20109a3fae92402cb76ad709ec5256bcd169","lessThan":"4506e229b2e468b8c64bcf52c50c41a3bf2e633e","status":"affected","versionType":"git"},{"version":"c6bf20109a3fae92402cb76ad709ec5256bcd169","lessThan":"44be85af3e1772ffb3332feafedad2a73b22854c","status":"affected","versionType":"git"},{"version":"c6bf20109a3fae92402cb76ad709ec5256bcd169","lessThan":"bda8324270b1ac91bfba1df8928e0570e29759e8","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wireless/mediatek/mt76/mt7615/main.c"],"versions":[{"version":"5.8","status":"affected"},{"version":"0","lessThan":"5.8","status":"unaffected","versionType":"semver"},{"version":"5.15.221","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.188","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.157","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.109","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.50","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.4","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"5.15.221"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"6.1.188"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"6.6.157"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"6.12.109"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"6.18.50"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"7.2.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/36c73b86a09f0e51c0f81a75c8945b6c5557ff27"},{"url":"https://git.kernel.org/stable/c/33d29aeb4c0eede92622a7d04ea492b94c30f089"},{"url":"https://git.kernel.org/stable/c/ef2ec8b537c3a54e241d693bd03016f80d0d4484"},{"url":"https://git.kernel.org/stable/c/3114d479f2a1d31b2e6214c395794c6e5715e579"},{"url":"https://git.kernel.org/stable/c/4506e229b2e468b8c64bcf52c50c41a3bf2e633e"},{"url":"https://git.kernel.org/stable/c/44be85af3e1772ffb3332feafedad2a73b22854c"},{"url":"https://git.kernel.org/stable/c/bda8324270b1ac91bfba1df8928e0570e29759e8"}],"title":"wifi: mt76: mt7615: avoid waiting for mac work under the mt76 mutex","x_generator":{"engine":"bippy-1.2.0"}}}}
