If a grace period elapses in between,\nthe cleanup operates on freed memory.\n\nRun mt76_reset_device() first, so the wcid entries are cleaned up and\ncleared while the links are still valid.","state":0,"publishedAt":"2026-09-17T16:09:02.189+00:00","modifiedAt":"2026-10-19T09:02:12.676+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                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"ace5d3b6b49e8391beb4d7244348ba7da5298878\",\n                            \"lessThan\": \"2b10eb3636d0c4cb6b763e045ec1294dbd70f5ad\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"ace5d3b6b49e8391beb4d7244348ba7da5298878\",\n                            \"lessThan\": \"8826d7a5e2dd727aa96456ccd58b33d2b080e935\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"ace5d3b6b49e8391beb4d7244348ba7da5298878\",\n                            \"lessThan\": \"7e4208e9f6a876c2b7d28fdb6b86dff3b05db2f7\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\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                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.18\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.18\",\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/2b10eb3636d0c4cb6b763e045ec1294dbd70f5ad","https://git.kernel.org/stable/c/8826d7a5e2dd727aa96456ccd58b33d2b080e935","https://git.kernel.org/stable/c/7e4208e9f6a876c2b7d28fdb6b86dff3b05db2f7"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-90356","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-90356","identifiers":["CVE-2026-90356"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
