{"id":"CVE-2026-53101","summary":"wifi: mt76: mt7921: fix potential deadlock in mt7921_roc_abort_sync","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7921: fix potential deadlock in mt7921_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 mt7921_mac_sta_remove() -\u003e\nmt7921_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":"2026-07-08T08:13:43.129935428Z","published":"2026-06-24T16:30:37.871Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53101.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/35180c772f5e11e2fa4d80d3dfd50906cb6d9646"},{"type":"WEB","url":"https://git.kernel.org/stable/c/91e77840bf13de3add125060cf8b32ca24a52c8c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b4faaa617af3f4173e64169b0ec1af8f9c5bca10"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d5059e52fd8bc624ec4255c9fa01a266513d126b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53101.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53101"},{"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":"352d966126e66d825244f1185eb9f2d904c83dd4"},{"fixed":"b4faaa617af3f4173e64169b0ec1af8f9c5bca10"},{"fixed":"35180c772f5e11e2fa4d80d3dfd50906cb6d9646"},{"fixed":"91e77840bf13de3add125060cf8b32ca24a52c8c"},{"fixed":"d5059e52fd8bc624ec4255c9fa01a266513d126b"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53101.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.9.0"},{"fixed":"6.12.95"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"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-2026-53101.json"}}],"schema_version":"1.7.5"}
