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:
