GHSA-C62V-4W5F-P7PW

Vulnerability from github – Published: 2024-11-19 03:31 – Updated: 2024-11-27 18:34

Details

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:

Severity ?

5.5 (Medium)
