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

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

The buffer length check before calling uvc_parse_format() 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
uvc_parse_format().
