Answer in brief
CVE-2026-21399 records a Medium severity (CVSS 6.9) vulnerability in CISA ADP Vulnrichment. The current sources do not mark it as known exploited. The current feed maps n/a/Intel(R) Open Volume Kernel Library (Intel(R) Open VKL) library maintained by intel(R) (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 6.9. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
