CVE-2026-20717: Denial of Service 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 a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. 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 (low), integrity (low) 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 affects Intel(R) QAT software drivers for Windows prior to version 1.13 due to improper input validation in Ring 3 user applications. An unprivileged, authenticated local attacker can trigger a denial of service condition with low complexity and no user interaction required. The CVSS 4.0 base score is 6.9, reflecting local attack vector, low complexity, no user interaction, and high impact on availability. Confidentiality and integrity impacts are rated low but do not result in actual system compromise. No vendor advisory or patch information is currently available.
Potential Impact
The vulnerability can cause denial of service on affected systems running vulnerable Intel QAT drivers, impacting availability. Confidentiality and integrity impacts are rated low but do not translate into actual data compromise or system integrity loss. There are no known exploits in the wild, and the attack requires local authenticated access with low complexity.
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 and monitor for unusual application behavior related to Intel QAT drivers. Do not assume the vulnerability is mitigated without vendor confirmation.
