Published May 27, 2026EPSS 0.16%

Overview

CVE-2026-45854 is a medium-severity vulnerability. It was published on May 27, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

crypto: inside-secure/eip93 - unregister only available algorithm

EIP93 has an options register. This register indicates which crypto

algorithms are implemented in silicon. Supported algorithms are

registered on this basis. Unregister algorithms on the same basis.

Currently, all algorithms are unregistered, even those not supported

by HW. This results in panic on platforms that don't have all options

implemented in silicon.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

How can CyberStrike help with CVE-2026-45854?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-45854 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
