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.","state":0,"publishedAt":"2026-09-17T16:09:15.361+00:00","modifiedAt":"2026-10-19T09:02:34.912+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/mt7996/mac.c\",\n                        \"drivers/net/wireless/mediatek/mt76/mt7996/main.c\",\n                        \"drivers/net/wireless/mediatek/mt76/mt7996/mt7996.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"d6f6b3a65660d183ef33f5a6582fd3b47174fe5a\",\n                            \"lessThan\": \"5183b9f092fc0041618f38f895bd0ad860c26ca9\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"85cd5534a3f2ec93e7d88713a77df5b4255520df\",\n                            \"lessThan\": \"0a951ff6704db7b46c3f6d03b77e6053122be8ab\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"85cd5534a3f2ec93e7d88713a77df5b4255520df\",\n                            \"lessThan\": \"ce35ecffc96e6d097d27b6fe30677a2cfe2e0461\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"6.18.33\",\n                            \"lessThan\": \"6.18.52\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\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/mt7996/mac.c\",\n                        \"drivers/net/wireless/mediatek/mt76/mt7996/main.c\",\n                        \"drivers/net/wireless/mediatek/mt76/mt7996/mt7996.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.19\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.19\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.52\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.6\",\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/5183b9f092fc0041618f38f895bd0ad860c26ca9","https://git.kernel.org/stable/c/0a951ff6704db7b46c3f6d03b77e6053122be8ab","https://git.kernel.org/stable/c/ce35ecffc96e6d097d27b6fe30677a2cfe2e0461"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-90376","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-90376","identifiers":["CVE-2026-90376"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
