This is not necessary since we don't use these "too recent" kernels, but
thanks for offering.
Here's a curious tweet:

Who the fuck DDoS'ed full-disclosure? ;)

Two of the files in the tarball have timestamps of 2012-07-14. Of
course, this is no proof, but it does appear that the bug was privately
known since about July 2012. The README says:
"A trimmed down version of an old exploit for the recently published
`sock_diag_handlers[]' vulnerability :("
The code contains:
printf("Linux kernel >= 3.2 NETLINK_INET_DIAG 0day\n");
printf("by huku <huku _at_ grhack _dot_ net>\n");
Is ">= 3.2" an error (should have been ">= 3.3" as your original posting
in here said)? (The difference may be whether Ubuntu 12.04 is affected.)
