Denial of Service Vulnerability in Intel QAT Software Drivers for Windows

CVE-2026-20793

What is CVE-2026-20793?

The vulnerability arises due to an unchecked return value in certain Intel QAT software drivers for Windows prior to version 1.13. It allows unprivileged adversaries with authenticated access to potentially cause a denial of service via local attack methods. Importantly, this access does not require special knowledge and operates without user interaction, which could allow an attacker to disrupt services. While the impact on confidentiality and integrity is not significant, the availability of the affected system may be compromised.
