CVE-2026-41606: Apache Thrift: c_glib dispatch stack overflow

Uncontrolled Recursion vulnerability in Apache Thrift. This issue affects Apache Thrift: before 0.23.0. Users are recommended to upgrade to version 0.23.0, which fixes the issue.

Security readout for executives and security teams

Plain-English summary

Apache Thrift versions before 0.23.0 can recurse until a process stack overflows, causing service interruption. The public record rates this high because it is network reachable, low complexity, needs no authentication or user interaction, and affects availability rather than data confidentiality or integrity.

Executive priority

Treat this as a high-priority availability risk for systems relying on Apache Thrift. It is not described as data theft or privilege escalation, but unauthenticated remote service disruption can still affect business operations.

Technical view

CVE-2026-41606 is an uncontrolled recursion issue in Apache Thrift c_glib dispatch, mapped to CWE-606 and CWE-674. The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, indicating unauthenticated remote denial-of-service potential. Apache says versions before 0.23.0 are affected and 0.23.0 fixes it.

Likely exposure

Exposure is most likely where applications or services use Apache Thrift before 0.23.0, particularly C GLib dispatch code. Downstream exposure may depend on vendor packaging, including Red Hat advisories listed in the source bundle.

Exploitation context

The provided sources do not report active exploitation, and KEV status is false. The risk comes from the CVSS profile: remote, low-complexity, unauthenticated availability impact. Public trigger details are limited in the supplied bundle.

Researcher notes

Evidence identifies uncontrolled recursion in c_glib dispatch but does not include trigger mechanics. Avoid assuming broader language bindings or products without dependency evidence. Focus validation on version provenance, generated C GLib usage, and vendor-fixed package mapping.

Mitigation direction

  • Upgrade Apache Thrift to version 0.23.0 or later.
  • Apply relevant downstream vendor fixes from Red Hat or other package providers.
  • Prioritize internet-facing or unauthenticated Thrift services first.
  • Check vendor advisories for product-specific backports or mitigations.

Validation and detection

  • Inventory applications and packages using Apache Thrift.
  • Confirm deployed Apache Thrift versions are 0.23.0 or fixed vendor builds.
  • Identify services using Thrift C GLib dispatch paths.
  • Review service monitoring for unexplained crashes or restart loops.
