Detects anomalous process execution patterns involving netkit devices and virtual network interfaces (VXLAN/OVS) configured with oversized headroom, characteristic of the TUNderflow (CVE-2026-81000) exploitation chain. The rule monitors for the staging of netkit devices and specific OVS command-line interactions by non-privileged accounts, excluding known legitimate SDN and CNI infrastructure management processes.

This rule detects kernel crash signatures (e.g., use-after-free, kernel panic) in the pppoe module, correlated with preceding anomalous activity related to PPPoEject or PPPoE socket manipulation. It identifies potential exploitation of CVE-2026-68121 on non-gateway devices.

Detects a suspected exploitation attempt of CVE-2026-81000, known as TUNderflow. The detection looks for a sequence of events where a process initializes a user namespace (unshare) followed by a kernel panic or error report from the tun/tap driver originating from the same process lineage within a short timeframe, which is indicative of an integer overflow exploit leading to kernel instability.

This rule detects kernel-level stability issues or crashes (ah6/ipsec related) occurring immediately after the execution of processes that create new user namespaces (unshare, clone with CLONE_NEWUSER). This pattern is often associated with exploitation of kernel vulnerabilities, where namespace manipulation is a prerequisite for triggering a crash or privilege escalation.

This rule identifies Linux devices running kernel versions susceptible to the DirtyAH6, TUNderflow, PPPoEject, and DiagSpill vulnerabilities. It parses the kernel version from the OSBuild information and flags devices falling below the specific patched versions (5.10.270, 6.1.188, 6.6.157, 7.2.4).

This rule detects a high volume of SCTP traffic targeted at internal systems, characterized by mass endpoint creation. This behavior is indicative of an exploit attempt against the 'sctp_diag' kernel component (CVE-2026-74469), which can lead to an out-of-bounds (OOB) write condition, potentially resulting in system instability or denial of service.

Detects the execution of the Linux 'unshare' utility to create new namespaces (user or network). This command is often used as a primitive for container escapes or privilege escalation by allowing an unprivileged user to create isolated environments. The rule excludes common container management and virtualization tools to reduce noise.
