FAUCET Score

CVE-2008-3526 describes an integer overflow vulnerability in the Stream Control Transmission Protocol (SCTP) implementation of the Linux kernel (versions 2.6.24-rc1 through 2.6.26.3). Specifically, the sctp_setsockopt_auth_key function is affected, allowing remote attackers to trigger a denial of service (system panic) or potentially other unspecified impacts through a crafted sca_keylength field. This vulnerability has a high severity CVSS score of 7.8, indicating it can be exploited remotely with low attack complexity and without authentication, leading to a complete loss of availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage for this CVE.
