CVE-2026-112270 · SGLang through 0.5.22 Memory Exhaustion via Mooncake STAGING_RSP chunk_idx
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
SGLang through 0.5.22 with the Mooncake disaggregation backend contains an uncontrolled memory allocation vulnerability in handle_staging_rsp() that lets unauthenticated network-adjacent attackers exhaust Prefill memory. Attackers can obtain the rank address from the /route endpoint and send STAGING_RSP messages with huge chunk_idx values under fresh room IDs, causing the scheduler to be OOM-killed.
