DescriptionCVE.org

Buffer overflow for some Intel(R) QAT Windows software before version 2.6.0. within Ring 3: User Applications may allow an escalation of privilege. System software adversary with an authenticated user combined with a low complexity attack may enable data manipulation. 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 (high) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

AnalysisAI
