CVE-2010-4251 describes a denial-of-service vulnerability in the Linux kernel's socket implementation (net/core/sock.c) affecting versions prior to 2.6.34, including various enterprise Linux distributions and VMware ESX. This flaw allows remote attackers to exhaust system memory by sending a large volume of network traffic, specifically UDP packets, due to improper management of received packet backlogs. Rated with a CVSS score of 7.5 (High), the vulnerability is easily exploitable over the network with low attack complexity and no user interaction, leading to high availability impact. Despite its severity, there is no evidence of active exploitation, no public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage.
