Frontier LLMs have reduced Linux privilege escalation discovery costs to approximately $1,280 per vulnerability, with 948 flaws identified across open-source kernels. Only 12.5% of AI-disclosed findings carry a known upstream patch, while exploitation remains at the historical 1.3% baseline. Remediation is human-bound, creating a triage bottleneck where detection outpaces verified patch deployment. NIST is responding with an AI incident response roadmap and an evaluation of AI-driven remediation to address critical infrastructure and embedded software exposure.
