Denial of Service Vulnerability in Linux Kernel do_fork Function via CLONE_VM

oval:org.mitre.oval:def:2819

The do_fork function in Linux 2.4.x before 2.4.26 and 2.6.x before 2.6.6 does not properly decrement the mm_count counter when an error occurs after the mm_struct for a child process has been activated which triggers a memory leak that allows local users to cause a denial of service (memory exhaustion) via the clone (CLONE_VM) system call.
