CVE-2026-20914 (GCVE-0-2026-20914)
Vulnerability from cvelistv5 – Published: 2026-05-12 16:35 – Updated: 2026-05-12 17:07

VEX
Summary
Null pointer dereference for some Intel(R) QAT software drivers for Windows before version 2.6.0 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 (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Mitigation MIT-56
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Requirements
Select a programming language that is not susceptible to these issues.
Mitigation
Implementation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Architecture and Design
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Implementation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
