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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-476"],"references":["https://bugzilla.redhat.com/show_bug.cgi?id=2069736","https://github.com/torvalds/linux/commit/00b5f37189d24ac3ed46cb7f11742094778c46ce","https://github.com/torvalds/linux/commit/7ec37d1cbe17d8189d9562178d8b29167fe1c31a","https://github.com/torvalds/linux/commit/b1e34d325397a33d97d845e312d7cf2a8b646b44","https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html"],"products":["debian:debian_linux","fedoraproject:fedora","linux:linux_kernel","redhat:enterprise_linux"],"source":"nvd","synced_at":"2026-10-19T21:35:14.992143698+00:00"},"epss":{"cve":"CVE-2022-2153","score":0.00468,"percentile":0.40214,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
