Description
libmikmod before 3.3.14 contains a heap out-of-bounds read vulnerability in the Impulse Tracker loader load_it.c that allows attackers to read adjacent heap memory via oversized patterns. Attackers can supply a crafted IT module with more than 200 pattern rows, causing IT_ConvertTrack() to read past the itpat buffer and crash applications.

Technical Analysis
CVE-2026-105838 is a heap out-of-bounds read vulnerability in libmikmod prior to version 3.3.14. The vulnerability exists in the Impulse Tracker loader (load_it.c) where an attacker can supply a specially crafted IT module containing more than 200 pattern rows. This triggers the IT_ConvertTrack() function to read adjacent heap memory beyond the itpat buffer, leading to an out-of-bounds read and application crash.
Potential Impact
An attacker can cause applications using vulnerable versions of libmikmod to crash by providing a malicious IT module with oversized pattern rows. This results in a denial of service due to heap out-of-bounds reads. There is no indication from the data that this vulnerability leads to code execution or information disclosure beyond the crash.
Mitigation Recommendations
A fix is available in libmikmod version 3.3.14. Users should upgrade to version 3.3.14 or later to remediate this vulnerability. No other mitigation guidance is provided or necessary as the vulnerability is addressed by the official patch.
