CVE-2025-67749
PCSX2 has an Out-of-bounds Read due to unchecked offset and size passed to memcpy
Description
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.

Action Type Old Value New Value Added Translation Title: pcsx2, Description: PCSX2 es un emulador de PlayStation 2 (PS2) gratuito y de código abierto. En las versiones 2.5.377 e inferiores, un desplazamiento y tamaño no verificados utilizados en una operación memcpy dentro de los manejadores CDVD SCMD 0x91 y SCMD 0x8F de PCSX2 permiten que una imagen de disco o ELF especialmente diseñada cause una lectura fuera de límites de la memoria del emulador. Debido a que el desplazamiento y el tamaño se controlan a través de los campos de encabezado MG, un ELF especialmente diseñado puede leer datos más allá de los límites de mg_buffer y hacer que se reflejen de nuevo en la memoria emulada. Este problema se corrige en la versión 2.5.378. -
