Overview

CVE-2025-38386 is a high-severity vulnerability. It was published on July 25, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

ACPICA: Refuse to evaluate a method if arguments are missing

As reported in [1], a platform firmware update that increased the number

of method parameters and forgot to update a least one of its callers,

caused ACPICA to crash due to use-after-free.

Since this a result of a clear AML issue that arguably cannot be fixed

up by the interpreter (it cannot produce missing data out of thin air),

address it by making ACPICA refuse to evaluate a method if the caller

attempts to pass fewer arguments than expected to it.

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.
