Since mt76_set_channel() also acquires\ndev-\u003emutex, this results in a deadlock.\n\nUse __mt76_set_channel() instead of mt76_set_channel().\nAdd cancel_delayed_work_sync() for mac_work before acquiring the mutex\nin mt76_remain_on_channel() to prevent a secondary deadlock with the\nmac_work workqueue.","modified":"2026-07-16T03:32:07.506751323Z","published":"2026-06-24T16:30:37.216Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53100.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5fc8c5d45e44575dda9fcabdc2aac4ad97baf0cd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6939b97ddad3cf3dfbb3b5a0a12ef79cb886747e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7a89c245d203aa0ed5ff2d68ac05b48b2ef9fa3f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53100.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53100"},{"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":"a8f424c1287cc79a06c21816658feea87dfcb83f"},{"fixed":"5fc8c5d45e44575dda9fcabdc2aac4ad97baf0cd"},{"fixed":"7a89c245d203aa0ed5ff2d68ac05b48b2ef9fa3f"},{"fixed":"6939b97ddad3cf3dfbb3b5a0a12ef79cb886747e"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-53100.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.14.0"},{"fixed":"6.18.33"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-53100.json"}}],"schema_version":"1.7.5"}
