Overview

CVE-2024-50288 is a high-severity vulnerability. It was published on November 19, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

media: vivid: fix buffer overwrite when using > 32 buffers

The maximum number of buffers that can be requested was increased to

64 for the video capture queue. But video capture used a must_blank

array that was still sized for 32 (VIDEO_MAX_FRAME). This caused an

out-of-bounds write when using buffer indices >= 32.

Create a new define MAX_VID_CAP_BUFFERS that is used to access the

must_blank array and set max_num_buffers for the video capture queue.

This solves a crash reported by:

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.
