CVE-2026-80594

Published Aug 28, 2026

Overview

CVE-2026-80594 is a known-severity vulnerability. It was published on August 28, 2026.

Technical Description

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

Input: ims-pcu - fix potential infinite loop in CDC union descriptor parsing

The driver parses CDC union descriptors in ims_pcu_get_cdc_union_desc()

by iterating through the extra descriptor data. However, it does not

verify that the bLength of each descriptor is at least 2. A malicious

device could provide a descriptor with bLength = 0, leading to an

infinite loop in the driver.

Add a check to ensure bLength is at least 2 before proceeding with

parsing.

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.
