CVE-2026-92867Network attack vectorHinoki check available

Code execution via malformed watchdog failover message

Published Sep 30, 2026 · Updated Sep 30, 2026

Out-of-bounds write in Pgpool-II 3.5 through 4.7.2 allows remote authenticated users to corrupt memory through watchdog failover messages. Watchdog failover processing accepts a malformed request and writes an attacker-controlled 32-bit value to an unintended memory address. Exploitation requires an enabled, reachable watchdog and can crash a Pgpool-II process or execute arbitrary code.
