CVE-2008-5300

CVE-2008-5300 describes a denial-of-service vulnerability in Linux kernel 2.6.28, where a local attacker can trigger a "soft lockup" and process loss by making numerous sendmsg calls that exploit a flaw in AF_UNIX garbage collection, leading to an out-of-memory condition. With a CVSS score of 4.9 (AV:L/AC:L/Au:N/C:N/I:N/A:C), this vulnerability is of medium severity, requiring local access with low attack complexity to achieve a complete availability impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this decade-old flaw.
