CVE-2005-0001: Race condition in the page fault handler (fault.c) for Linux kernel 2.2.x to 2.2.7, 2.4 to 2.4.29, and 2.6...

Security readout for executives and security teams

CVE-2005-0001 is an old Linux kernel local privilege issue. On multiprocessor systems, a race in stack expansion handling could let a local user run code with elevated privileges. Modern supported Linux releases should not be affected, but legacy servers, appliances, or forgotten virtual machine images may still carry risk. Exposure is mainly legacy Linux systems, embedded appliances, or archived workloads running affected kernels on multiprocessor hardware. Internet-facing access is not required, but an attacker needs local code execution or an account on the host. Low for normal modern fleets, high for any legacy Linux estate. This should be handled as a cleanup and isolation priority unless affected systems support critical business services or allow untrusted local users. Mitigation focus: Inventory Linux hosts and appliances for affected kernel branches.; Apply the relevant vendor kernel security update where still available.; Upgrade or retire unsupported Linux 2.2, 2.4, and early 2.6 systems..
