CVE-2011-2183

CVE-2011-2183 describes a race condition in the Linux kernel's KSM feature (Kernel SamePage Merging) affecting versions prior to 2.6.39.3. This vulnerability allows a local attacker to trigger a denial of service (NULL pointer dereference) and potentially other unspecified impacts through a crafted application. The CVSS score of 4.0 indicates a low severity, requiring high attack complexity from a local attacker to achieve a denial of service. While there is no evidence of active exploitation or Metasploit modules, an ExploitDB entry (EDB-35820) exists for a local denial of service, and the CVE has received minimal community discussion or media coverage.
