EPSS
3.6%
EPSS pct
88th
Exploited
No known
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.
