CVE-2026-47483Network attack vector

Service interruption via concurrent profiling requests

Published Jul 28, 2026 · Updated Jul 28, 2026

Resource exhaustion in NVIDIA DCGM 4.5.2 and earlier and DCGM Exporter 4.8.2 and earlier allows remote attackers to interrupt service. The /debug/pprof handlers process concurrent profiling requests without limiting the work or resources consumed. Network access to an exporter with pprof enabled and unauthenticated permits resource exhaustion and disclosure of goroutines, heap data, arguments, and profiles.
