CVE-2025-14369

Application crash via untrusted frame-count allocation

Published Jan 20, 2026 · Updated Jan 20, 2026

Integer overflow in mackron dr_flac 0 through 0.13.2 allows attackers to crash consuming applications with a crafted FLAC file. The full-file decode helper trusts the totalPCMFrameCount metadata value and uses it to size one allocation before decoding, so a tiny file can request excessive memory. Exploitation requires an application to process attacker-controlled FLAC input and is limited to a crash or abnormal behavior from memory exhaustion.
