Overview

CVE-2026-52904 is a medium-severity vulnerability. It was published on June 9, 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/nouveau: fix nvkm_device leak on aperture removal failure

When aperture_remove_conflicting_pci_devices() fails during probe, the

error path returns directly without unwinding the nvkm_device that was

just allocated by nvkm_device_pci_new(). This leaks both the device

wrapper and the pci_enable_device() reference taken inside it.

Jump to the existing fail_nvkm label so nvkm_device_del() runs and

balances both. The leak was introduced when the intermediate

nvkm_device_del() between detection and aperture removal was dropped

in favor of creating the pci device once.

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.
