**Name of the Vulnerable Software and Affected Versions** Linux kernel versions 2.4.x through 2.6.17 **Description** The issue is related to the perfmonctl system call in the Linux kernel, which does not properly track the reference count for file descriptors when running on Itanium systems. This allows local users to cause a denial of service by consuming file descriptors. **Recommendations** For Linux kernel versions 2.4.x through 2.6.17, consider upgrading to a version 2.6.18 or later to resolve the issue. As a temporary workaround, restrict access to the sys perfmonctl system call to minimize the risk of exploitation.
