Vulnerability from fkie_nvd - Published: 2024-11-19 02:16 - Updated: 2026-06-17 08:04
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
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: https://bugzilla.kernel.org/show_bug.cgi?id=219258
