In some\ncases Xen emulates the instruction by replaying it, using an executable\nstub.  Some instructions may raise an exception, which is supposed to be\nhandled gracefully.  Certain replayed instructions have additional logic\nto set up and recover the changes to the arithmetic flags.\n\nFor replayed instructions where the flags recovery logic is used, the\nmetadata for exception handling was incorrect, preventing Xen from\nhandling the the exception gracefully, treating it as fatal instead.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","score":4.3},"cwes":["CWE-755"],"references":["https://xenbits.xenproject.org/xsa/advisory-470.html","http://www.openwall.com/lists/oss-security/2025/07/01/1","http://xenbits.xen.org/xsa/advisory-470.html"],"products":["xen:xen"],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-27465","score":0.00705,"percentile":0.53382,"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).
