CVE-2026-111166 Details
Description
libmikmod through 3.3.15 contains a heap out-of-bounds read vulnerability in the IMF_Load() loader that allows attackers to read beyond allocated memory by supplying a crafted IMF module. Attackers can enable the linear-period header flag and map notes to out-of-range samples, causing noteindex indexing far past the heap allocation and crashing applications that load the file.
A heap out-of-bounds read vulnerability has been identified in libmikmod versions through 3.3.15, specifically within the IMF_Load() module loader. This vulnerability allows attackers to read beyond allocated memory by providing a crafted IMF module that exploits the linear-period header flag. The manipulation maps notes to out-of-range samples, causing the noteindex to access memory far beyond the allocated heap, potentially leading to application crashes when the file is loaded.
To address this vulnerability, the IMF loader should be modified to correctly handle note-to-sample mappings, ensuring that all indices are within valid bounds before accessing memory. Additionally, libmikmod's channel-count validation should be applied to the MTM loader to prevent similar out-of-bounds reads.
