CVE-2005-4811: The hugepage code (hugetlb.c) in Linux kernel 2.6, possibly 2.6.12 and 2.6.13, in certain configurations, a...

Security readout for executives and security teams

This is an old Linux kernel local denial-of-service issue. On affected Linux 2.6 systems, a local user could trigger a kernel crash through hugepage memory handling. Business risk is mainly service outage on legacy servers or appliances that still run vulnerable kernels. Exposure is most likely on unsupported or embedded Linux systems still running affected 2.6 kernels with hugepage support enabled. Risk increases where untrusted local shell, application, or shared-hosting users can execute code. Moderate priority for most organizations because exploitation requires local access and causes outage rather than data theft. Raise priority for legacy, shared, or appliance-heavy environments where old Linux kernels remain in production. Mitigation focus: Check vendor advisories for affected kernel packages and supported upgrade paths.; Apply the relevant vendor kernel update where available.; Prioritize multi-user, shared-hosting, and appliance environments first..
