Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 2.6.37.2
Description
The issue is related to the epoll implementation in the Linux kernel, which does not properly traverse a tree of epoll file descriptors. This allows local users to cause a denial of service, specifically CPU consumption, by using a crafted application that makes
epoll create and epoll ctl system calls.Recommendations
For Linux kernel versions prior to 2.6.37.2, consider upgrading to a newer version to resolve the issue. As a temporary workaround, restrict the use of the
epoll create and epoll ctl system calls to minimize the risk of exploitation.Exploitability
