Yes—if an NVIDIA DCGM Exporter instance has its Go /debug/pprof profiling endpoints enabled and reachable, unauthenticated concurrent requests may exhaust resources and crash the exporter. The reported impact is loss of GPU monitoring, not a flaw that inherently crashes NVIDIA GPUs. Operators should verify their installed versions and endpoint exposure, then follow NVIDIA’s current security bulletin and restrict access.
What CVE-2026-47483 affects
CVE-2026-47483 concerns NVIDIA DCGM Exporter, a monitoring component that exposes GPU metrics for collection by systems such as Prometheus. The reported issue is in Go runtime profiling endpoints served at /debug/pprof, not in GPU hardware itself.

According to Threadlinqs Intelligence’s incident account, some profiling requests can remain open for a caller-specified duration. A large number of concurrent, unauthenticated requests may raise memory use until the exporter runs out of resources and crashes. That would interrupt metrics collection and visibility into GPU health; resource pressure could also affect training or inference workloads sharing the host. These are reported mechanics and impacts, not a guarantee that every deployment is vulnerable or will fail in the same way.

Which versions are affected
The incident account’s summary of NVIDIA Security Bulletin 5857 lists DCGM Exporter versions 0.0 through 4.8.2 as affected and 4.8.2 as updated. Because that summary includes the stated update version in the affected range, it does not establish a clear inclusive fixed-version boundary. The same account lists DCGM versions 0.0 through 4.5.2 as affected and 4.5.3 as updated.
Do not infer that DCGM Exporter 4.8.2 is definitively vulnerable or fixed from that ambiguous summary. Check NVIDIA Security Bulletin 5857 for its current affected and fixed-version guidance, and compare it with the exact exporter and DCGM packages deployed in your environment. NVIDIA’s Product Security page says that from October 1, 2026, bulletins are published on GitHub in Markdown, CSAF, and CVE formats while the website and repository run in parallel; follow NVIDIA’s bulletin guidance for updates and mitigations.

When a server is exposed
Risk depends on configuration and network reachability. The incident account identifies port 9400 as DCGM Exporter’s default and says profiling is opt-in in current versions. An installation with profiling disabled, or one whose endpoint is reachable only from a trusted private network, is not equivalent to a publicly reachable instance with profiling enabled.
Lava’s four Shodan scans from March through May 2026, as reported by Threadlinqs Intelligence, observed about 2,100 GPU servers across roughly 300 organizations with unauthenticated DCGM metrics exposed to the internet, covering more than 12,000 GPU UUIDs. The account says about 25% of those exposed DCGM hosts also exposed /debug/pprof. These are scan observations from that period, not a census of GPU servers or proof that every observed host was exploitable. The same account separately reports 12,096 publicly exposed Prometheus Node Exporter hosts; that is a distinct finding, not a count of vulnerable DCGM Exporter systems.
Quick Recap
How to reduce exposure
- Identify what is actually deployed. Check the DCGM Exporter and DCGM package versions on each relevant host or container, then compare them with NVIDIA Security Bulletin 5857. Apply the fixed versions NVIDIA identifies for your installation.
- Check profiling configuration. Determine whether
--enable-pprofis set. Leave profiling disabled unless it is explicitly needed. If profiling must remain enabled, block/debug/pprofat a proxy or network layer where appropriate. - Limit network reachability. Do not expose DCGM Exporter, Node Exporter, or Prometheus directly to the public internet. Bind the exporter to loopback or a private interface where practical, and restrict port 9400 and related monitoring access with firewall rules or security groups so only authorized infrastructure can connect.
- Constrain and monitor the service. Set CPU and memory limits for the exporter. Alert when GPU metric scrape targets disappear, and monitor for unexpected external traffic to profiling endpoints so a monitoring outage is visible promptly.
What to check on your deployment
- The exact DCGM Exporter and DCGM versions, checked against NVIDIA’s current bulletin.
- Whether profiling is enabled and whether
/debug/pprofresponds from any untrusted network. - Whether port 9400 is bound to a public interface or permitted by a public-facing firewall or security group.
- Whether resource limits and alerts for missing GPU metrics are in place.
