For\nexample, on the AP side, if a station's setup link is the 5G link and\nthe station uses 2G to transmit a frame, the value of non_aql_packets\nis increased on the 5G wcid but decreased on the 2G wcid. Once the\ninflated counter exceeds MT_MAX_NON_AQL_PKT, the TX scheduler\npermanently refuses to service the station.\n\nDrop the reassignment and account on the wcid used for transmission.\nThis also records the actual wcid in the queue entry."}],"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/tx.c"],"versions":[{"version":"e1378e5228aaa1bf6bb253a379c7de1722a94e00","lessThan":"f85f6933cc170155f1c7c2dffdd014965787c71b","status":"affected","versionType":"git"},{"version":"e1378e5228aaa1bf6bb253a379c7de1722a94e00","lessThan":"fc7fae55255ccbde009232e84b102d2782a69ecf","status":"affected","versionType":"git"},{"version":"e1378e5228aaa1bf6bb253a379c7de1722a94e00","lessThan":"186c957ac3325aefb982567ffdd3654b283688a7","status":"affected","versionType":"git"},{"version":"e1378e5228aaa1bf6bb253a379c7de1722a94e00","lessThan":"8ae659743ba936b22ecb4620815887728e2820d6","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/tx.c"],"versions":[{"version":"5.10","status":"affected"},{"version":"0","lessThan":"5.10","status":"unaffected","versionType":"semver"},{"version":"6.12.110","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.52","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.6","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":"5.10","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/f85f6933cc170155f1c7c2dffdd014965787c71b"},{"url":"https://git.kernel.org/stable/c/fc7fae55255ccbde009232e84b102d2782a69ecf"},{"url":"https://git.kernel.org/stable/c/186c957ac3325aefb982567ffdd3654b283688a7"},{"url":"https://git.kernel.org/stable/c/8ae659743ba936b22ecb4620815887728e2820d6"}],"title":"wifi: mt76: fix non-AQL packet accounting for MLO stations","x_generator":{"engine":"bippy-1.2.0"}}}}
