- Summary
- media: vivid: fix buffer overwrite when using > 32 buffers
- 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 mustblank array that was still sized for 32 (VIDEOMAX_FRAME). This caused an out-of-bounds write when using buffer indices >= 32.
Create a new define MAXVIDCAPBUFFERS that is used to access the mustblank array and set maxnumbuffers for the video capture queue.
