Description
Heap-based buffer overflow for the Intel(R) Open Volume Kernel Library (Intel(R) Open VKL) library maintained by intel(R) before version 2.0.2 within Ring 3: User Applications may allow a denial of service. System 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 (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
