Published Oct 21, 2024 linux CWE-476 EPSS 0.24% (15th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-49911 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 function pointer in dcn20_set_output_transfer_func

This commit adds a null check for the set_output_gamma function pointer

in the dcn20_set_output_transfer_func function. Previously,

set_output_gamma was being checked for null at line 1030, but then it

was being dereferenced without any null check at line 1048. This could

potentially lead to a null pointer dereference error if set_output_gamma

is null.

To fix this, we now ensure that set_output_gamma is not null before

dereferencing it. We do this by adding a null check for set_output_gamma

before the call to set_output_gamma at line 1048.

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.
