CVE-2025-26306Public exploitNetwork attack vector

Denial of service via unreleased string buffers

Published Feb 20, 2025 · Updated Feb 24, 2025

Memory leak in libming 0.4.8 allows remote attackers to exhaust memory and interrupt service by supplying a crafted file. The readSizedString function in util/read.c allocates an initial 256-byte string buffer and does not release it when processing fails or returns early. A user must cause an application built with the library to process the file; repeated processing can deplete memory without exposing or altering data.
