CVE-2009-2526 describes an infinite loop denial-of-service vulnerability in Microsoft Windows Vista and Server 2008. The flaw stems from improper validation of SMBv2 packet fields, allowing a remote, unauthenticated attacker to cause a system hang by sending a specially crafted packet to the Server service. With a CVSS score of 7.8 (high), this vulnerability is easily exploitable over the network with low attack complexity, leading to a complete loss of system availability. While not listed on CISA's KEV catalog, exploit code for related issues in the srv2.sys component exists on ExploitDB, though direct exploitation of this specific infinite loop vulnerability is not explicitly detailed. Community discussion and media coverage for this CVE are minimal.
