Overview

CVE-2026-45976 is a medium-severity vulnerability. It was published on May 27, 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/amdgpu: Fix memory leak in amdgpu_ras_init()

When amdgpu_nbio_ras_sw_init() fails in amdgpu_ras_init(), the function

returns directly without freeing the allocated con structure, leading

to a memory leak.

Fix this by jumping to the release_con label to properly clean up the

allocated memory before returning the error code.

Compile tested only. Issue found using a prototype static analysis tool

and code review.

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.
