Overview

CVE-2022-49137 is a medium-severity vulnerability. It was published on February 26, 2025 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/amd/amdgpu/amdgpu_cs: fix refcount leak of a dma_fence obj

This issue takes place in an error path in

amdgpu_cs_fence_to_handle_ioctl(). When `info->in.what` falls into

default case, the function simply returns -EINVAL, forgetting to

decrement the reference count of a dma_fence obj, which is bumped

earlier by amdgpu_cs_get_fence(). This may result in reference count

leaks.

Fix it by decreasing the refcount of specific object before returning

the error code.

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.
