NOTE: because this issue is due to incorrect use of the Intel specification, it should have been split into separate identifiers; however, there was some value in preserving the original mapping of the multi-codebase coordinated-disclosure effort to a single identifier.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-119"],"references":["http://blog.illumos.org/2012/06/14/illumos-vulnerability-patched/","http://blog.xen.org/index.php/2012/06/13/the-intel-sysret-privilege-escalation/","http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2012-003.txt.asc","http://lists.xen.org/archives/html/xen-announce/2012-06/msg00001.html","http://lists.xen.org/archives/html/xen-devel/2012-06/msg01072.html"],"products":["citrix:xenserver","freebsd:freebsd","illumos:illumos","joyent:smartos","microsoft:windows_7","microsoft:windows_server_2003","microsoft:windows_server_2008","microsoft:windows_xp","netbsd:netbsd","sun:sunos","xen:xen"],"source":"nvd","synced_at":"2026-10-19T20:24:00.973572543+00:00"},"epss":{"cve":"CVE-2012-0217","score":0.39835,"percentile":0.98624,"date":"2026-10-31"},"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).
