CVE-2010-4805

HIGH 7.5EPSS 3.59%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (3.59%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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-2010-4251.
