Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

libmikmod 3.3.14 之前的版本在 load_dsm.c 文件中的 DSM_Load() 函数中存在一个整数溢出漏洞，攻击者可通过构造特制的曲目数量触发堆缓冲区溢出。攻击者可以提供一个 DSM 模块，使其 numchn 与 numpat 的乘积发生 16 位整型回绕（wrap around），从而覆盖堆内存，导致程序崩溃或潜在的特权代码执行。
