CVE-2026-46331 act_pedit Module Load or tc pedit Filter Add by Non-Root Process

This rule detects suspicious activity patterns on Linux systems that may indicate privilege escalation or container escape attempts. It monitors three main behaviors: the execution of network configuration tools (tc, insmod, modprobe) for kernel-level manipulations (pedit/actions), the use of 'unshare' to create isolated namespaces, and typical privilege escalation commands (su, id, whoami, bash) executed by non-root users. The rule correlates these events and alerts based on the combination and intensity of these behaviors, flagging high-severity activity when kernel-level tools are combined with namespace manipulation or privilege elevation.
