Summary
media: uvcvideo: Fix 1-byte out-of-bounds read in uvc_parse_format()
Details

In the Linux kernel, the following vulnerability has been resolved:

media: uvcvideo: Fix 1-byte out-of-bounds read in uvcparseformat()

The buffer length check before calling uvcparseformat() only ensured that the buffer has at least 3 bytes (buflen > 2), buf the function accesses buffer[3], requiring at least 4 bytes.

This can lead to an out-of-bounds read if the buffer has exactly 3 bytes.

Fix it by checking that the buffer has at least 4 bytes in uvcparseformat().
