CVE-2007-0001

CVE-2007-0001 describes a local denial-of-service vulnerability affecting the Red Hat Enterprise Linux 4 kernel (2.6.9). An attacker can trigger a kernel panic by replacing a file being monitored by the audit subsystem's file watch (auditctl -w), as the old inode's watch is not properly dropped. This vulnerability has a CVSS score of 4.7, indicating a medium attack complexity and high impact on availability, but requires local access. While not actively exploited in the wild, a proof-of-concept exploit exists on ExploitDB, though there is minimal community discussion or media coverage surrounding this decade-old flaw.
