CVE-2006-3741 is a medium vulnerability (CVSS 4.9) in Linux Kernel, published October 9, 2006. No source lists public exploit code. EPSS puts the chance of exploitation in the next 30 days at 0.44%, the 38th percentile. Fixed in kernel-source-2.6.8 2.6.8-16sarge6.
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).
