Updating the IRTE if and only if the new GSI is an\nMSI results in KVM leaving an IRTE posting to a vCPU.\n\nThe dangling IRTE can result in interrupts being incorrectly delivered to\nthe guest, and in the worst case scenario can result in use-after-free,\ne.g. if the VM is torn down, but the underlying host IRQ isn't freed.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-416"],"references":["https://git.kernel.org/stable/c/023816bd5fa46fab94d1e7917fe131b79ed1fb41","https://git.kernel.org/stable/c/116c7d35b8f72eac383b9fd371d7c1a8ffc2968b","https://git.kernel.org/stable/c/3066ec21d1a33896125747f68638725f456308db","https://git.kernel.org/stable/c/3481fd96d801715942b6f69fe251133128156f30","https://git.kernel.org/stable/c/9bcac97dc42d2f4da8229d18feb0fe2b1ce523a2"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:22.920403922+00:00"},"epss":{"cve":"CVE-2025-37885","score":0.00316,"percentile":0.24293,"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).
