CVE-2008-2136 describes a memory leak vulnerability in the Linux kernel's Simple Internet Transition (SIT) tunnel interface, specifically within the ipip6_rcv function. This flaw affects Linux kernel versions 2.4 before 2.4.36.5 and 2.6 before 2.6.25.3, impacting various distributions including Canonical and Debian. Remote attackers can exploit this by sending crafted network traffic to a SIT tunnel interface, leading to memory consumption and a denial of service. The vulnerability carries a CVSS score of 7.8 (High), indicating a critical severity. It requires no authentication (AV:N/AC:L/Au:N) and can be exploited with low complexity, resulting in a complete loss of availability (A:C). The FAUCET Risk Score is 91/100, highlighting its significant potential impact. Despite its high severity, there is no evidence of active exploitation, nor are there publicly available exploit modules in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are minimal, suggesting it has not garnered significant attention from the broader security community.
