Published Oct 21, 2024 linux CWE-476 EPSS 0.24% (14th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-49901 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/msm/adreno: Assign msm_gpu->pdev earlier to avoid nullptrs

There are some cases, such as the one uncovered by Commit 46d4efcccc68

("drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails")

where

msm_gpu_cleanup() : platform_set_drvdata(gpu->pdev, NULL);

is called on gpu->pdev == NULL, as the GPU device has not been fully

initialized yet.

Turns out that there's more than just the aforementioned path that

causes this to happen (e.g. the case when there's speedbin data in the

catalog, but opp-supported-hw is missing in DT).

Assigning msm_gpu->pdev earlier seems like the least painful solution

to this, therefore do so.

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.
