CVE-2026-80679

Published Aug 28, 2026

Overview

CVE-2026-80679 is a known-severity vulnerability. It was published on August 28, 2026.

Technical Description

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

s390/dasd: Fix potential NULL pointer dereference

dasd_release_space() checks the implementation of the is_ese()

discipline function before calling it to determine if a given device is

an ESE DASD.

The current usage of the logical AND operator will lead to a NULL

pointer dereference as the function is called even if the function

pointer is NULL.

Fix this by using the logical OR operator.

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.
