Hi,

The following vulnerability was published for pcsx2.

CVE-2025-67749[0]:
| PCSX2 is a free and open-source PlayStation 2 (PS2) emulator. In
| versions 2.5.377 and below, an unchecked offset and size used in a
| memcpy operation inside PCSX2's CDVD SCMD 0x91 and SCMD 0x8F
| handlers allow a specially crafted disc image or ELF to cause an
| out-of-bounds read from emulator memory. Because the offset and size
| is controlled through MG header fields, a specially crafted ELF can
| read data beyond the bounds of mg_buffer and have it reflected back
| into emulated memory. This issue is fixed in version 2.5.378.


If you fix the vulnerability please also make sure to include the
