CVE request: kernel: remote buffer overflow in bluetooth

[Dan Rosenberg <dan.j.rosenberg () gmail com>]

A remote user can provide a small value for the command size field in
the command header of an l2cap configuration request, resulting in an
integer underflow when subtracting the size of the configuration request
header.  This results in copying a very large amount of data via
memcpy() and destroying the kernel heap. [1]
