{"id":"CVE-2022-47946","details":"An issue was discovered in the Linux kernel 5.10.x before 5.10.155. 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.","modified":"2026-03-14T11:55:56.152955Z","published":"2022-12-23T22:15:08.773Z","references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2022/12/27/1"},{"type":"FIX","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.10.161&id=0f544353fec8e717d37724d95b92538e1de79e86"},{"type":"EVIDENCE","url":"https://www.openwall.com/lists/oss-security/2022/12/22/2"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"5.10"},{"fixed":"5.10.155"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-47946.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
