NVIDIA DCGM Exporter Flaw CVE-2026-47483 Lets Attackers Crash GPU Monitoring

NVIDIA patched CVE-2026-47483, a high-severity vulnerability in DCGM Exporter (CVSS 8.2) where unauthenticated attackers can abuse profiling endpoints to exhaust memory and crash GPU monitoring; researchers found ~2,100 publicly exposed exporters reporting ~12,000 GPUs. No confirmed in-the-wild exploitation has been reported; recommended mitigations include upgrading to 4.8.2+, disabling pprof unless needed, binding exporters to non-routable interfaces, and restricting access with firewalls or security groups.
