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.","state":0,"publishedAt":"2022-08-31T00:00:00+00:00","modifiedAt":"2026-10-14T13:07:01.983+00:00","affected":[{"ecosystem":"Vendor product","name":"kernel","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n/a\",\n                    \"product\": \"kernel\",\n                    \"versions\": [\n                        {\n                            \"version\": \"kernel 5.18\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://bugzilla.redhat.com/show_bug.cgi?id=2069736","https://www.openwall.com/lists/oss-security/2022/06/22/1","https://github.com/torvalds/linux/commit/7ec37d1cbe17d8189d9562178d8b29167fe1c31a","https://github.com/torvalds/linux/commit/00b5f37189d24ac3ed46cb7f11742094778c46ce","https://github.com/torvalds/linux/commit/b1e34d325397a33d97d845e312d7cf2a8b646b44","https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html","https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2022-2153","license":"CVE Program Terms of Use","key":"cve-program:CVE-2022-2153","identifiers":["CVE-2022-2153"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
