Overview

CVE-2026-53141 is a medium-severity vulnerability. It was published on June 25, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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:

drm/v3d: Fix global performance monitor reference counting

In the SET_GLOBAL ioctl, v3d_perfmon_find() bumps the reference count on

the perfmon it returns, but v3d_perfmon_set_global_ioctl() and

v3d_perfmon_delete() fail to release that reference on several paths:

1. v3d_perfmon_set_global_ioctl() leaks the reference on its error

paths.

2. CLEAR_GLOBAL leaks both the find reference and the reference

previously stashed in v3d->global_perfmon by the SET_GLOBAL ioctl

that configured it.

3. Destroying a perfmon that is the current global perfmon leaks the

reference stashed by the SET_GLOBAL ioctl.

Release each of these references explicitly.

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.

How can CyberStrike help with CVE-2026-53141?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-53141 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
