CVE-2026-68176

Published Aug 10, 2026 EPSS 0.21% (11th pctl)

Overview

CVE-2026-68176 is a known-severity vulnerability. It was published on August 10, 2026.

Technical Description

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

tracing: Fix mmiotrace possible NULL dereferencing of hiter->dev

If the mmio_pipe_open() fails to find a PCI device, the hiter->dev

will be assigned to NULL. The mmiotrace read() function dereferences the

hiter->dev if hiter exists.

Change the test of the read to not only check hiter being NULL, but also

the hiter->dev before dereferencing 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.
