CVE-2023-30637Network attack vector

Service interruption via unreleased server allocation

Published Apr 13, 2023 · Updated Feb 7, 2025

Memory leakage in Baidu braft 1.1.2 allows remote attackers to interrupt the atomic server through unauthenticated network access. brpc::Server::StartInternal allocates a 56-byte object with operator new when the atomic server starts and fails to release it before process termination. The public report documents one startup leak but provides no request sequence that repeats the allocation or demonstrates service interruption.
