1) Resource exhaustion (CVE-ID: CVE-2006-3741)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The perfmonctl system call (sys_perfmonctl) in Linux kernel 2.4.x and 2.6 before 2.6.18, when running on Itanium systems, does not properly track the reference count for file descriptors, which allows local users to cause a denial of service (file descriptor consumption).
