Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 0.62% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Go standard library net and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 30 daysRemediation target: Within 180 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Distribution package intelligence

Release-specific package status

Alpine, Debian findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.

6 package states
Repository candidate not checked

A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

CVE-2026-39836 · CSAF 2.0 · revision 3 · finalRed Hat Product Securitynet: golang: Go net package: Denial of Service via NUL byte in Dial and LookupPort on Windows
4 known affected

The vendor explicitly identifies these products as affected by this CVE.

  • multicluster-engine/maestro-rhel9 as a component of Multicluster Engine for Kubernetes
  • oadp/oadp-velero-rhel9 as a component of OpenShift API for Data Protection
  • openshift-pipelines-client.src as a component of OpenShift Pipelines
  • rhtas/ec-rhel9 as a component of Red Hat Trusted Artifact Signer
Summary
A flaw was found in the `net` package of Go (golang). When running on Windows, the `Dial` and `LookupPort` functions can panic if they receive an input containing a NUL (0) byte. This can be triggered by a remote attacker providing a specially crafted input, leading to a denial of service (DoS) for applications using these functions.

01

What, why and how

The Dial and LookupPort functions panic on Windows when provided with an input containing a NUL (0).

What

The Dial and LookupPort functions panic on Windows when provided with an input containing a NUL (0).

Why

An exception is thrown from a function, but it is not caught.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

What

The Dial and LookupPort functions panic on Windows when provided with an input containing a NUL (0).

How

02

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Uncaught Exception → cause the confidentiality, integrity or availability impact described by the vendor

Privileges required
None: unauthenticated exploitation is possible
