Overview

CVE-2025-38428 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:

Input: ims-pcu - check record size in ims_pcu_flash_firmware()

The "len" variable comes from the firmware and we generally do

trust firmware, but it's always better to double check. If the "len"

is too large it could result in memory corruption when we do

"memcpy(fragment->data, rec->data, len);"

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.
