Out-of-Bounds Read in Hyperscan Affects User Applications by Intel

CVE-2026-40424

What is CVE-2026-40424?

A vulnerability in Intel's Hyperscan prior to version v5.4.2.1 allows an out-of-bounds read through user applications. This could enable a denial of service by an unprivileged adversary with local access, requiring no user interaction. Although the attack model is low complexity, it poses potential risks to system availability, while impacts on confidentiality and integrity are minimal. Users of affected versions should consider applying updates to mitigate any potential exposure.
