NO PAUSE...\".\n\nRoot cause:\nIf the MLD_ID field in the TXD is neither the primary link id nor the\nsecondary link id, it may lead to a firmware busy loop when the third\nlink is in power saving mode.\n\nRemap frames directed to a third link to the primary link wcid. Since\nTX status events and txfree completions carry the wcid the firmware\nsaw, use the remapped wcid for packet id tracking and non-AQL packet\naccounting as well, while the frame keeps its original link context\nfor addressing, band and OMAC selection."}],"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/mt7996/mac.c","drivers/net/wireless/mediatek/mt76/mt7996/main.c","drivers/net/wireless/mediatek/mt76/mt7996/mt7996.h"],"versions":[{"version":"d6f6b3a65660d183ef33f5a6582fd3b47174fe5a","lessThan":"5183b9f092fc0041618f38f895bd0ad860c26ca9","status":"affected","versionType":"git"},{"version":"85cd5534a3f2ec93e7d88713a77df5b4255520df","lessThan":"0a951ff6704db7b46c3f6d03b77e6053122be8ab","status":"affected","versionType":"git"},{"version":"85cd5534a3f2ec93e7d88713a77df5b4255520df","lessThan":"ce35ecffc96e6d097d27b6fe30677a2cfe2e0461","status":"affected","versionType":"git"},{"version":"6.18.33","lessThan":"6.18.52","status":"affected","versionType":"semver"}]},{"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/mt7996/mac.c","drivers/net/wireless/mediatek/mt76/mt7996/main.c","drivers/net/wireless/mediatek/mt76/mt7996/mt7996.h"],"versions":[{"version":"6.19","status":"affected"},{"version":"0","lessThan":"6.19","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":"6.18.33","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.19","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.19","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/5183b9f092fc0041618f38f895bd0ad860c26ca9"},{"url":"https://git.kernel.org/stable/c/0a951ff6704db7b46c3f6d03b77e6053122be8ab"},{"url":"https://git.kernel.org/stable/c/ce35ecffc96e6d097d27b6fe30677a2cfe2e0461"}],"title":"wifi: mt76: mt7996: fix MLD ID in MAC TXD and HIF TXP","x_generator":{"engine":"bippy-1.2.0"}}}}
