CVE-2023-31517Network attack vector

Service interruption via crafted-file memory retention

Published May 23, 2023 · Updated Jul 9, 2026

Memory leak in CConsole::Chain in Teeworlds 0.7.5 allows remote attackers to interrupt the application by opening a crafted file. The component retains memory while processing the file, but public references do not identify the allocation, ownership error, or missing release path. No authentication or user interaction is required; successful exploitation consumes available memory until the affected process is interrupted.
