{"id":"CVE-2026-53103","summary":"wifi: mt76: mt7925: fix potential deadlock in mt7925_roc_abort_sync","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7925: fix potential deadlock in mt7925_roc_abort_sync\n\nroc_abort_sync() can deadlock with roc_work(). roc_work() holds\ndev-\u003emt76.mutex, while cancel_work_sync() waits for roc_work()\nto finish. If the caller already owns the same mutex, both\nsides block and no progress is possible.\n\nThis deadlock can occur during station removal when\nmt76_sta_state() -\u003e mt76_sta_remove() -\u003e\nmt7925_mac_sta_remove_link() -\u003e mt7925_mac_link_sta_remove() -\u003e\nmt7925_roc_abort_sync() invokes cancel_work_sync() while\nroc_work() is still running and holding dev-\u003emt76.mutex.\n\nThis avoids the mutex deadlock and preserves exactly-once\nwork ownership.","modified":"2026-10-08T02:51:25.365102056Z","published":"2026-06-24T16:30:39.184Z","related":["SUSE-SU-2026:22742-1","SUSE-SU-2026:22769-1","SUSE-SU-2026:22812-1","SUSE-SU-2026:22835-1","openSUSE-SU-2026:21388-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53103.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/153bcba36c87a1ba555b57b6c49028d5812f895b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2d8e0053bca29143ace51e08c980ff076844a4b0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dd08ca3f092f4185ece69ce2a835c23198b1628a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53103.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53103"},{"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":"45064d19fd3af6aeb0887b35b5564927980cf150"},{"fixed":"153bcba36c87a1ba555b57b6c49028d5812f895b"},{"fixed":"2d8e0053bca29143ace51e08c980ff076844a4b0"},{"fixed":"dd08ca3f092f4185ece69ce2a835c23198b1628a"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.11.2"},{"fixed":"6.12"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"978d1756b3ae1b857826eb7ed8181f3c5180dce9"}]}],"versions":["v6.11.11","v6.11.10","v6.11.9","v6.11.8","v6.11.7","v6.11.6","v6.11.5","v6.11.4","v6.11.3","v6.11.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53103.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.12.0"},{"fixed":"6.18.33"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53103.json"}}],"schema_version":"1.9.0"}
