  permission changes when programs executed. A local attacker could hold open
  files to examine details about programs running with higher privileges,
  potentially increasing the chances of exploiting additional
  vulnerabilities. (CVE-2011-1020)

  Dan Rosenberg discovered that the X.25 Rose network stack did not correctly
  handle certain fields. If a system was running with Rose enabled, a remote
  attacker could send specially crafted traffic to gain root privileges.
  (CVE-2011-1493)
  
  Dan Rosenberg discovered that the DCCP stack did not correctly handle
  certain packet structures. A remote attacker could exploit this to crash
  the system, leading to a denial of service. (CVE-2011-1770)
  
  Vasiliy Kulikov discovered that taskstats listeners were not correctly
  handled. A local attacker could expoit this to exhaust memory and CPU
  resources, leading to a denial of service. (CVE-2011-2484)
  
  It was discovered that Bluetooth l2cap and rfcomm did not correctly
  initialize structures. A local attacker could exploit this to read portions
  of the kernel stack, leading to a loss of privacy. (CVE-2011-2492)";
