CVE-2006-1066

CVE-2006-1066 describes a denial-of-service vulnerability in Linux kernel versions 2.6.16-rc2 and earlier, specifically impacting x86_64 systems with preemption enabled. A local attacker can trigger an "oops" by repeatedly performing single-step ptrace tasks, leading to DEBUG_STACK corruption during the do_debug function. The CVSS score of 1.2 indicates low severity, requiring local access and high attack complexity, with only a partial denial of service as the impact. There is no known exploit code available in Metasploit, Nuclei, or ExploitDB, and the vulnerability shows no evidence of active exploitation or community discussion.
