CVE-2011-1547 describes multiple stack consumption vulnerabilities in the NetBSD kernel (versions 4.0, 5.0 before 5.0.3, and 5.1 before 5.1.1) when IPsec is enabled. This vulnerability allows remote attackers to trigger a denial of service (memory corruption and system panic) or potentially other unspecified impacts through specially crafted IPv4 or IPv6 packets containing nested IPComp headers. With a CVSS score of 6.8, it is considered a medium-severity issue, requiring medium attack complexity but no authentication, and impacting confidentiality, integrity, and availability. While there is an ExploitDB entry (EDB-17097) detailing kernel memory corruption, there is no evidence of active exploitation, Metasploit or Nuclei modules, or significant community discussion or media coverage.
