CVE-2026-105837: Integer Overflow or Wraparound in sezero libmikmod
Description
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.

Technical Analysis
The vulnerability in libmikmod versions prior to 3.3.14 involves an integer overflow or wraparound in the DSM_Load() function. Specifically, the product of the numchn and numpat fields in a DSM module can overflow a 16-bit integer, causing a heap buffer overflow. This memory corruption can be triggered by supplying a specially crafted DSM module file, potentially leading to denial of service or arbitrary code execution.
Potential Impact
Successful exploitation can cause heap memory corruption resulting in application crashes or potentially arbitrary code execution. The vulnerability requires local access (AV:L) and user interaction (UI:P), with no privileges required (PR:N). The overall impact is high due to the possibility of code execution and denial of service.
Mitigation Recommendations
A fixed version 3.3.14 of libmikmod addresses this vulnerability. Users should upgrade to libmikmod version 3.3.14 or later to remediate this issue. No vendor advisory content is provided, so patch status is inferred from the affectedVersions field indicating the fix in 3.3.14.
