CVE-2004-0427 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.47% chance of exploitation in the next 30 days.
