Description Vladimir Vasilev 2026-10-07 10:44:34 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
