Linux kernel 2.6.23 allows local users to create low pages in virtual userspace memory and bypass mmap_min_addr protection via a crafted executable file that calls the do_brk function.

Security readout for executives and security teams

This is an old Linux kernel hardening bypass. A local user on Linux kernel 2.6.23 could create memory pages where mmap_min_addr was meant to prevent them. The source bundle does not prove direct privilege escalation, active exploitation, or a named fixed release. Exposure is likely limited to legacy systems running Linux kernel 2.6.23 or close vendor-derived builds. Modern supported Linux distributions are unlikely to run this kernel, but embedded, appliance, or long-lived systems should be checked. Treat this as a legacy exposure check, not an emergency, unless Linux 2.6.23 exists in sensitive environments. The business risk is highest where untrusted users can run local code on obsolete systems. Mitigation focus: Inventory systems for Linux kernel 2.6.23 or vendor-derived builds.; Check kernel.org and distribution advisories for vendor-confirmed fixes.; Prioritize replacement of unsupported legacy kernels where found..
