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.","state":0,"publishedAt":"2022-12-23T00:00:00+00:00","modifiedAt":"2026-10-14T18:39:45.467+00:00","affected":[{"ecosystem":"Vendor product","name":"n/a","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n/a\",\n                    \"product\": \"n/a\",\n                    \"versions\": [\n                        {\n                            \"version\": \"n/a\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://www.openwall.com/lists/oss-security/2022/12/22/2","https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.10.161&id=0f544353fec8e717d37724d95b92538e1de79e86","http://www.openwall.com/lists/oss-security/2022/12/27/1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2022-47946","license":"CVE Program Terms of Use","key":"cve-program:CVE-2022-47946","identifiers":["CVE-2022-47946"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
