{"id":"CVE-2022-2153","details":"A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service.","modified":"2026-03-15T14:46:07.961278Z","published":"2022-08-31T16:15:10.837Z","related":["SUSE-SU-2022:3897-1","SUSE-SU-2022:3929-1","SUSE-SU-2022:3930-1","SUSE-SU-2022:3998-1","SUSE-SU-2022:4053-1","SUSE-SU-2022:4072-1","SUSE-SU-2022:4272-1","SUSE-SU-2022:4273-1","SUSE-SU-2022:4573-1","SUSE-SU-2022:4574-1","SUSE-SU-2022:4589-1","SUSE-SU-2022:4614-1","SUSE-SU-2022:4615-1","SUSE-SU-2022:4617-1"],"references":[{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html"},{"type":"FIX","url":"https://www.openwall.com/lists/oss-security/2022/06/22/1"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2069736"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/00b5f37189d24ac3ed46cb7f11742094778c46ce"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/7ec37d1cbe17d8189d9562178d8b29167fe1c31a"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/b1e34d325397a33d97d845e312d7cf2a8b646b44"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"5.18"}]},{"events":[{"introduced":"0"},{"last_affected":"36"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]},{"events":[{"introduced":"0"},{"last_affected":"10.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-2153.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"}]}
