Summary

Game Music Emu (libgme) through 0.6.5 contains a global out-of-bounds read in Classic_Emu::mute_voices_ (CWE-125). An NSF file whose voice count exceeds the 16-entry voice-type table makes the library read past the static array during loading. An attacker can craft an NSF header with chip_flags 0x3F and open it with gme_open_data or gme_open_file to crash the application, a denial of service. The CVSS 4.0 base score is 6.8 (MEDIUM); CISA SSVC lists exploitation as poc, the references include an exploit link, and the CVE is not in CISA KEV.
