MediumCVSS 5.5/10Last modified Oct 21, 2026

Description

ValleyBell libvgm through commit a6eed945 contains a heap out-of-bounds read vulnerability in the PCM data-block decompressor caused by an unbounded compression-table index. Attackers can supply a crafted .vgm file with a small type 0x7F table and wider compressed values, causing DecompressDataBlk to over-read heap memory and crash consumers.
