This rule detects Linux kernel crashes or faults (e.g., kernel BUG, panic, use-after-free, slab-out-of-bounds) that occur shortly after the execution of suspicious utilities or processes known to be associated with kernel exploitation or container escape attempts (e.g., unshare, dirtyah6, tunderflow). By correlating crash logs with preceding process execution, it identifies potential post-exploitation activity or exploit testing.

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.
Detects potential local privilege escalation (LPE) to root via an unshare invocation, tracking the process lineage from an unprivileged unshare execution to the subsequent spawning of a root-privileged shell within a short time window. This pattern is characteristic of various Linux kernel vulnerability exploits such as DirtyAH6, TUNderflow, PPPoEject, and DiagSpill, where the unshare system call is abused to enter new user namespaces to bypass security restrictions.

Detects interactive or ad-hoc loading of the SCTP kernel module, which can be indicative of an adversary attempting to gain kernel-level persistence or capabilities. The rule excludes common system-initiated module loads from package managers and system service managers to reduce noise.
