CVE-2026-94650
Description
A flaw was found in Apache Thrift. An uncontrolled recursion vulnerability in the C (GLib) library bindings allows a remote, unauthenticated attacker to send specially crafted input to an affected application. Processing this input triggers excessive nested function calls that exhaust stack memory, causing an application crash and resulting in a Denial of Service (DoS).
Statement
This vulnerability is rated as an Important severity flaw because an unauthenticated remote attacker can trigger a denial of service by submitting specially crafted requests that induce deep recursion and exhaust system memory. The issue is strictly confined to applications and services using Apache Thrift's C GLib language bindings to handle untrusted network communications. Deployments that do not expose services built with these specific bindings, or that use alternative Thrift language libraries, are not affected.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
