CVE-2026-43631 · llama.cpp b7492–b9060 Use-After-Free RCE via llama-server
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
llama.cpp builds b7492 through the latest b9060 contains a use-after-free vulnerability in the vocab pointer of llama-server when the --sleep-idle-seconds feature is enabled, allowing unauthenticated remote attackers to execute arbitrary code. Attackers can trigger the vulnerability by sending requests to affected endpoints while the server transitions to sleep mode, causing concurrent worker threads to dereference a freed vocab pointer that can be reclaimed with attacker-controlled data to achieve remote code execution.
