CVE-2026-110660— vgmstream through r2117 Stack Out-of-Bounds Read via G.722.1/Siren14 Decoder

Quick assessment

Affected
vgmstream vgmstream
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.

在 r2117 之前的 vgmstream 版本中，G.722.1/Siren14 解码器（位于 g7221_lib.c 文件中）存在一个栈上越界读取漏洞。该漏洞的位读取器在刷新数据时未检查 data_u32 数组的边界。攻击者可以构造恶意的 .s14 或 .sss 文件，在格式检测过程中驱动 decode_vector_quantized_mlt_indices() 函数超出栈缓冲区范围，从而导致应用程序崩溃。

Vulnerability Description
vgmstream through r2117 contains a stack out-of-bounds read vulnerability in the G.722.1/Siren14 decoder in g7221_lib.c, whose bit reader refills without checking the data_u32 array end. Attackers can supply crafted .s14 or .sss files that drive decode_vector_quantized_mlt_indices() past the stack buffer during format detection, crashing the application.
