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.

Security readout for executives and security teams

CVE-2004-0427 is an old Linux kernel flaw that can let a local user exhaust system memory and cause denial of service. It affects Linux 2.4.x before 2.4.26 and 2.6.x before 2.6.6. The source bundle does not show remote exploitation or active exploitation. Exposure is most likely on legacy Linux systems running kernels older than 2.4.26 or 2.6.6, or vendor kernels that did not backport the fix. Internet exposure alone is not indicated; local account or local code execution is required by the description. Treat as a legacy-system availability risk. It is not supported by the bundle as an active internet-scale emergency, but any remaining affected kernels should be patched or retired because local users can crash business services. Mitigation focus: Upgrade affected Linux kernels to fixed vendor-supported versions.; Apply relevant vendor kernel advisories for Red Hat, Debian, Fedora, SUSE, Mandrake, or Turbolinux.; Retire systems still running unsupported Linux 2.4 or early 2.6 kernels..
