Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.2

Description The issue is related to the procfs implementation in the Linux kernel, where it does not properly interact with CLONE NEWPID clone system calls. This allows remote attackers to cause a denial of service by making many connections to a daemon that uses PID namespaces to isolate clients, resulting in a reference leak and memory consumption.

Recommendations For Linux kernel versions prior to 3.2, update to version 3.2 or later to resolve the issue.
