Overview

CVE-2026-43332 is a high-severity vulnerability. It was published on May 8, 2026 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:

thermal: core: Fix thermal zone device registration error path

If thermal_zone_device_register_with_trips() fails after registering

a thermal zone device, it needs to wait for the tz->removal completion

like thermal_zone_device_unregister(), in case user space has managed

to take a reference to the thermal zone device's kobject, in which case

thermal_release() may not be called by the error path itself and tz may

be freed prematurely.

Add the missing wait_for_completion() call to the thermal zone device

registration error path.

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.
