CVE-2026-20782: Denial of Service in Intel(R) QAT software drivers for Windows
Buffer overflow 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 involves a buffer overflow in Intel(R) QAT software drivers for Windows prior to version 1.13, which can be triggered by a low complexity attack from an unprivileged authenticated user with local access. The flaw can cause denial of service conditions affecting system availability. The CVSS 4.0 base score is 6.9, reflecting medium severity with local attack vector, low attack complexity, no user interaction, and partial impact on confidentiality and integrity but high impact on availability. No official remediation or patch information is currently available.
Potential Impact
The vulnerability can lead to denial of service, impacting the availability of systems running affected Intel QAT drivers. Confidentiality and integrity impacts are rated low and are not expected to result in further compromise. There are no known exploits in the wild at this time.
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 systems running vulnerable versions and monitor for unusual system behavior indicative of denial of service attempts.
