Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.89%). 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 2.6.34 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service (memory consumption) by sending a large amount of network traffic, as demonstrated by netperf UDP tests.
