CVE-2026-20767: Escalation of Privilege in Intel(R) QAT software drivers for Windows
Improper input validation for some Intel(R) QAT software drivers for Windows before version 1.13 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no 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.
AI Analysis
Technical Summary
This vulnerability arises from improper input validation in Intel(R) QAT software drivers for Windows prior to version 1.13, specifically within Ring 3 user applications. An attacker with local access and low complexity attack methods, combined with authenticated user privileges, may escalate their privileges. The CVSS 4.0 base score is 8.5, reflecting high impact on confidentiality, integrity, and availability. The vulnerability does not require user interaction and does not involve special internal knowledge. No official remediation or patch information is currently available.
Potential Impact
Successful exploitation could allow an unprivileged authenticated user to escalate their privileges on the affected system, potentially compromising confidentiality, integrity, and availability at a high level. However, there are no known exploits in the wild, and the vulnerability requires local access with authenticated user privileges.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict local access to trusted users and monitor for unusual privilege escalation attempts related to Intel QAT drivers.
