A use-after-free in io_sqpoll_wait_sq in fs/io_uring.c allows an attacker to crash the kernel, resulting in denial of service. finish_wait can be skipped. An attack can occur in some situations by forking a process and then quickly terminating it. NOTE: later kernel versions, such as the 5.15 longterm series, substantially changed the implementation of io_sqpoll_wait_sq."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://www.openwall.com/lists/oss-security/2022/12/22/2"},{"url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.10.161&id=0f544353fec8e717d37724d95b92538e1de79e86"},{"name":"[oss-security] 20221227 Re: Linux kernel: use-after-free in io_sqpoll_wait_sq","tags":["mailing-list"],"url":"http://www.openwall.com/lists/oss-security/2022/12/27/1"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T15:02:36.593Z"},"title":"CVE Program Container","references":[{"url":"https://www.openwall.com/lists/oss-security/2022/12/22/2","tags":["x_transferred"]},{"url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.10.161&id=0f544353fec8e717d37724d95b92538e1de79e86","tags":["x_transferred"]},{"name":"[oss-security] 20221227 Re: Linux kernel: use-after-free in io_sqpoll_wait_sq","tags":["mailing-list","x_transferred"],"url":"http://www.openwall.com/lists/oss-security/2022/12/27/1"}]},{"problemTypes":[{"descriptions":[{"type":"CWE","cweId":"CWE-416","lang":"en","description":"CWE-416 Use After Free"}]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":5.5,"attackVector":"LOCAL","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"timestamp":"2025-04-15T13:50:17.154893Z","id":"CVE-2022-47946","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-04-15T13:50:55.380Z"}}]}}
