Last modified

CVE-2010-4805 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 3.59% chance of exploitation in the next 30 days.
