CVE-2006-2374 describes a denial-of-service vulnerability in the Server Message Block (SMB) driver (MRXSMB.SYS) affecting Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 and earlier. A local attacker can trigger a system hang by manipulating a file handle related to the shadow device, leading to a deadlock. Rated Medium severity (CVSS 5.5), this vulnerability requires local access and user interaction is not needed for exploitation, resulting in a high impact on availability. While not listed in CISA's KEV catalog, exploit code for a local denial of service is publicly available on ExploitDB, though there is no evidence of active exploitation or significant community discussion.
