As an impact it is known to affect availability. CVE summarizes:

Null pointer dereference 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 (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

The advisory is available at intel.com. This vulnerability was named CVE-2026-20771 since 12/04/2025. The exploitation appears to be easy. Local access is required to approach this attack. The technical details are unknown and an exploit is not available.
