CVE-2026-41606Network attack vectorHinoki check available

Remote service crash via recursive c_glib dispatch

Published Apr 28, 2026 · Updated Aug 26, 2026

Uncontrolled recursion in Apache Thrift before 0.23.0 allows remote attackers to crash c_glib-based RPC servers with crafted requests. The c_glib request-dispatch path recursively processes attacker-controlled input without a depth bound until the process stack is exhausted. Exposure requires a network-reachable server using the affected c_glib binding; the bounded consequence is service interruption.
