[PATCH 0/1] [HARDY] [LUCID] [NATTY] [ONEIRIC] [PRECISE] [CVE-2012-2136] net: sock: validate data_len before allocating skb in sock_alloc_send_pskb()

[Brad Figg]

CVE-2012-2136

BugLink: http://bugs.launchpad.net/bugs/1006622

We need to validate the number of pages consumed by data_len, otherwise frags
array could be overflowed by userspace. So this patch validate data_len and
return -EMSGSIZE when data_len may occupies more frags than MAX_SKB_FRAGS.
