Overview

CVE-2024-49913 is a medium-severity vulnerability affecting linux linux_kernel. It was published on October 21, 2024 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/display: Add null check for top_pipe_to_program in commit_planes_for_stream

This commit addresses a null pointer dereference issue in the

`commit_planes_for_stream` function at line 4140. The issue could occur

when `top_pipe_to_program` is null.

The fix adds a check to ensure `top_pipe_to_program` is not null before

accessing its stream_res. This prevents a null pointer dereference.

Reported by smatch:

drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:4140 commit_planes_for_stream() error: we previously assumed 'top_pipe_to_program' could be null (see line 3906)

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
