Linux Kernel Vulnerabilities Trigger Moxa Security Advisory

Moxa published an urgent advisory for three critical Linux kernel vulnerabilities (CVE-2026-31431, CVE-2026-43284, CVE-2026-43500) affecting multiple industrial device series that can enable local privilege escalation and, in containerized environments, container escape to compromise hosts; the vendor provided interim mitigation (disable the rxrpc module) and step-by-step patching instructions for CTOS while a permanent kernel patch is prepared.
