Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Failure to validate peer credentials (ucred) on Netlink sockets allows local unprivileged users to inject arbitrary interface state changes by spoofing netlink messages. This bypasses the trust boundaries expected for kernel-only communications.

Denial of Service: An issue with buffer allocation limits during interface event consumption can trigger process panics, allowing local conditions or high volumes of platform events to crash the watcher daemon.
