Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires active user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.","score":5.4,"severity":"medium","published":"2026-11-10T16:28:02.389Z","modified":"2026-11-11T10:49:51.234Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"n/a","name":"Intel(R) Graphics Driver software installers","platforms":[],"versions":[{"version":"See references","status":"affected"}],"defaultStatus":"unaffected","cpes":[],"source":"intel","url":"https://www.cve.org/CVERecord?id=CVE-2026-20880"}],"remediation":[],"references":["https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01440.html"],"sources":[{"name":"CVE","id":"CVE-2026-20880","modified":"2026-11-11T10:49:51.234Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-20880"}],"assessments":[{"source":"intel","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":5.4}],"sourceAffected":[],"observedAt":"2026-11-11T22:54:51.006Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T22:35:32.718Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-11-11T06:55:32.838Z","attemptedAt":"2026-11-11T06:55:32.838Z"},{"source":"GHSA","status":"available","checkedAt":"2026-11-11T06:55:31.082Z","attemptedAt":"2026-11-11T06:55:31.082Z"},{"source":"EUVD","status":"available","checkedAt":"2026-11-11T06:55:32.846Z","attemptedAt":"2026-11-11T06:55:32.846Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-11-11T06:55:32.846Z","attemptedAt":"2026-11-11T06:55:32.846Z"}],"evidence":[{"source":"GitHub Advisory Database","id":"GHSA-73r4-qm6c-qp9g","url":"https://github.com/advisories/GHSA-73r4-qm6c-qp9g","modified":"2026-11-10T18:31:51Z","checkedAt":"2026-11-11T06:55:31.082Z"},{"source":"NVD","id":"CVE-2026-20880","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-20880","modified":"2026-11-11T05:19:44.000","score":5.4,"vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","checkedAt":"2026-11-11T06:55:32.838Z"},{"source":"ENISA EUVD","id":"EUVD-2026-121289","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-121289","modified":"Nov 11, 2026, 4:56:56 AM","score":5.4,"vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","checkedAt":"2026-11-11T06:55:32.846Z"}],"aiSummary":{"text":"Intel Graphics Driver software installers have incorrect default permissions, potentially allowing an unprivileged attacker with local access and user interaction to escalate privileges, impacting system confidentiality, integrity, and availability.
