Low risk2th percentile - higher than 2% of all known CVEs
Summary
Heap-based buffer overflow in Intel(R) Open Volume Kernel Library (Open VKL) before version 2.0.2 may allow denial of service. An attacker with an authenticated user and a low complexity attack can exploit this locally, without user interaction. The impact on integrity is low and on availability is high.
Risk Assessment
Risk of application crash in Open VKL due to buffer overflow, potentially affecting availability and data integrity.
Recommendation
Update Intel(R) Open Volume Kernel Library to version 2.0.2 or later to prevent DoS attacks.
Original NVD description (English source)
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.
