CVE-2026-74329

Published Aug 15, 2026 EPSS 0.17% (7th pctl)

Overview

CVE-2026-74329 is a known-severity vulnerability. It was published on August 15, 2026.

Technical Description

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

watchdog: unregister PM notifier on watchdog unregister

watchdog_register_device() registers wdd->pm_nb when

WDOG_NO_PING_ON_SUSPEND is set, but watchdog_unregister_device() does not

remove it. This leaves an embedded notifier block on the PM notifier chain

after the watchdog device has been unregistered.

A later suspend/resume notification can then call watchdog_pm_notifier()

with a stale watchdog_device pointer, or at minimum after wdd->wd_data has

been cleared by watchdog_dev_unregister().

Unregister the PM notifier before tearing down the watchdog device.

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.
