CVE-2004-0077: The do_mremap function for the mremap system call in Linux 2.2 to 2.2.25, 2.4 to 2.4.24, and 2.6 to 2.6.2,...

Security readout for executives and security teams

This is a legacy Linux kernel flaw that could let someone with local access become root. It affects very old Linux kernel lines: 2.2 through 2.2.25, 2.4 through 2.4.24, and 2.6 through 2.6.2. Exposure is most likely on obsolete, unpatched Linux systems or embedded appliances still running the listed kernel ranges. Current supported distributions should only be exposed if they retained an affected kernel without vendor fixes. Treat as high priority only where legacy Linux remains in service. The business risk is complete host compromise after local access, but applicability is narrow because the affected kernels are over two decades old. Mitigation focus: Identify systems running the affected Linux kernel ranges.; Apply fixed kernel packages from the relevant Linux vendor advisory.; Prioritize multi-user, shared hosting, and legacy internet-adjacent Linux systems..
