CVE-2026-20767: Escalation of Privilege in Intel(R) QAT software drivers for Windows
CVE-2026-20767 is a high-severity vulnerability in Intel(R) QAT software drivers for Windows versions before 1.13. It involves improper input validation in user-mode components (Ring 3) that may allow an authenticated, unprivileged local user to escalate privileges with low attack complexity and no user interaction. The vulnerability impacts confidentiality, integrity, and availability at a high level. No official patch or remediation level has been confirmed yet. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability affects Intel(R) QAT software drivers for Windows prior to version 1.13. It arises from improper input validation in user-mode components, enabling an authenticated but unprivileged local user to escalate privileges. The attack requires local access but no special user interaction or internal knowledge. The CVSS 4.0 base score is 8.5, reflecting high impact on confidentiality, integrity, and availability. No vendor advisory or patch information is currently available, and no exploits have been reported in the wild.
Potential Impact
Successful exploitation could allow a local authenticated user with low privileges to gain higher privileges on the affected system, potentially compromising system confidentiality, integrity, and availability at a high level. However, there are no reported exploits in the wild, and the vulnerability requires local access.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict local access to trusted users only and monitor for unusual privilege escalation attempts related to Intel QAT drivers.
