{"id":"CVE-2026-90376","summary":"wifi: mt76: mt7996: fix MLD ID in MAC TXD and HIF TXP","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7996: fix MLD ID in MAC TXD and HIF TXP\n\nProblem:\nMCU command timeout while the firmware state is normal, and the\nfirmware keeps showing the error log \"ERROR!! 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.","modified":"2026-09-19T03:47:26.092183003Z","published":"2026-09-17T16:09:15.361Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90376.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0a951ff6704db7b46c3f6d03b77e6053122be8ab"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5183b9f092fc0041618f38f895bd0ad860c26ca9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ce35ecffc96e6d097d27b6fe30677a2cfe2e0461"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90376.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90376"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"d6f6b3a65660d183ef33f5a6582fd3b47174fe5a"},{"fixed":"5183b9f092fc0041618f38f895bd0ad860c26ca9"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"85cd5534a3f2ec93e7d88713a77df5b4255520df"},{"fixed":"0a951ff6704db7b46c3f6d03b77e6053122be8ab"},{"fixed":"ce35ecffc96e6d097d27b6fe30677a2cfe2e0461"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.18.33"},{"fixed":"6.18.52"}]}],"versions":["v6.18.51","v6.18.50","v6.18.49","v6.18.48","v6.18.47","v6.18.46","v6.18.45","v6.18.44","v6.18.43","v6.18.42","v6.18.41","v6.18.40","v6.18.39","v6.18.38","v6.18.37","v6.18.36","v6.18.35","v6.18.34","v6.18.33"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90376.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90376.json"}}],"schema_version":"1.9.0"}
