Overview

CVE-2022-49451 is a high-severity vulnerability. It was published on February 26, 2025 and has a CVSS 3.1 base score of 8.4 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.4, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

firmware: arm_scmi: Fix list protocols enumeration in the base protocol

While enumerating protocols implemented by the SCMI platform using

BASE_DISCOVER_LIST_PROTOCOLS, the number of returned protocols is

currently validated in an improper way since the check employs a sum

between unsigned integers that could overflow and cause the check itself

to be silently bypassed if the returned value 'loop_num_ret' is big

enough.

Fix the validation avoiding the addition.

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.
