CVE Request: Linux: net: out-of-bounds due do a signedness issue when defragging ipv6

[Andrey Konovalov <andreyknvl () google com>]

Hi,

There is a bug in the Linux kernel ipv6 implementation, which leads to
an out-of-bounds write on ipv6 packet defragmentation.

A fix was sent upstream:

Could you assign a CVE for this?

Thanks!
