Technical details
A divide-by-zero vulnerability (CWE-369) exists in certain Intel QuickAssist Technology (QAT) software drivers for Windows before version 1.13. The flaw is located within Ring 3 (User Applications) components of the driver stack. An unprivileged but authenticated local adversary can trigger this condition through a low-complexity attack without requiring user interaction. Successful exploitation leads to a denial of service (DoS) by crashing the affected application or driver component. Intel has released version 1.13 and later to mitigate this issue.
