{"id":"CVE-2026-64305","summary":"crypto: qat - protect service table iterations with service_lock","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: qat - protect service table iterations with service_lock\n\nThe service_table list is protected by service_lock when entries are\nadded or removed (in adf_service_add() and adf_service_remove()), but\nseveral functions iterate over the list without holding this lock.\n\nA concurrent adf_service_register() or adf_service_unregister() call\ncould modify the list during traversal, leading to list corruption or\na use-after-free.\n\nFix this by holding service_lock across all list_for_each_entry()\niterations of service_table in adf_dev_init(), adf_dev_start(),\nadf_dev_stop(), adf_dev_shutdown(), adf_dev_restarting_notify(),\nadf_dev_restarted_notify(), and adf_error_notifier().\n\nThe lock ordering is safe: callers of the static helpers (adf_dev_up()\nand adf_dev_down()) acquire state_lock before service_lock, and no\nevent_hld callback or service_lock holder ever acquires state_lock in\nthe reverse order.","modified":"2026-07-27T04:03:21.107082065Z","published":"2026-07-25T08:49:39.536Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64305.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0dbcecea740d943002c1cbdafa39bdfc108e32a5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/222fa7b453b612f4407f260146d89a2ce2bc831d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5c6f845e77ec35f9b7b047cc8f9789bf397cdd3e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c3c5925791cff3b84d313293fd60f384d877d793"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64305.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64305"},{"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":"d8cba25d2c68992a6e7c1d329b690a9ebe01167d"},{"fixed":"222fa7b453b612f4407f260146d89a2ce2bc831d"},{"fixed":"c3c5925791cff3b84d313293fd60f384d877d793"},{"fixed":"0dbcecea740d943002c1cbdafa39bdfc108e32a5"},{"fixed":"5c6f845e77ec35f9b7b047cc8f9789bf397cdd3e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64305.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.17.0"},{"fixed":"6.12.96"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.39"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64305.json"}}],"schema_version":"1.7.5"}
