Original posting:

 remote denial of service
CVE-ID: CVE-2010-4805

The socket implementation in net/core/sock.c in the Linux kernel before 2.6.35 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service by sending a large amount of network traffic, related to the sk_add_backlog function and the sk_rmem_alloc socket field.  NOTE: this vulnerability exists because of an incomplete fix for CVE-YYYY-NNN.

Comment 1 Jiri Bohac 2011-06-07 10:05:32 UTC
Could this be a duplicate of Bug #655973? The upstream commit c377411f2494a931ff7facdbb3a6839b1266bcf6 got applied to our kernel trees already in the patch series from that bug.
Comment 2 Marcus Meissner 2011-06-08 13:45:27 UTC
yes, we got it already.

i checked sle11 sp1, it has the patch, same for sle10 sp3 and sp4.

so yes, it is fixed already.
