CVE-2006-3741

Linux kernel 2.4.x and 2.6 < 2.6.18 - Denial of Service via perfmonctl File Descriptor Reference Count

Title source: llm
STIX 2.1

Description

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).
