Doc Text:
A flaw was found in libmikmod. A local attacker can cause arbitrary code execution or a Denial of Service (DoS) by enticing a user to open a specially crafted DSM audio module. An integer overflow during track count processing in the DSM file loader leads to a heap-based buffer overflow that corrupts application memory.

Description OSIDB Bzimport 2026-10-06 13:46:54 UTC 
libmikmod before 3.3.14 contains an integer overflow vulnerability in DSM_Load() in load_dsm.c that allows attackers to trigger heap buffer overflow via crafted track counts. Attackers can supply a DSM module whose numchn and numpat product wraps a 16-bit value, overwriting heap memory to cause crashes or potential code execution.
