Overview

CVE-2024-49915 is a medium-severity vulnerability. 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 clk_mgr in dcn32_init_hw

This commit addresses a potential null pointer dereference issue in the

`dcn32_init_hw` function. The issue could occur when `dc->clk_mgr` is

null.

The fix adds a check to ensure `dc->clk_mgr` is not null before

accessing its functions. This prevents a potential null pointer

dereference.

Reported by smatch:

drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn32/dcn32_hwseq.c:961 dcn32_init_hw() error: we previously assumed 'dc->clk_mgr' could be null (see line 782)

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.
