Doc Text:
A flaw was found in the Intel Open Volume Kernel Library (Intel Open VKL). This heap-based buffer overflow vulnerability, present in user applications, could allow an authenticated local attacker to trigger a denial of service. This attack has low complexity and requires no user interaction, primarily impacting the availability of the system.

Description OSIDB Bzimport 2026-08-11 16:52:04 UTC 
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.
