{"id":"CVE-2025-67749","state":"PUBLISHED","title":"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.","publishedAt":"2025-12-12T22:24:57.520Z","updatedAt":"2025-12-15T14:59:28.999Z","severity":{"score":5.3,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["PCSX2 pcsx2"],"affected":[{"vendor":"PCSX2","product":"pcsx2","versions":[{"version":"< 2.5.378","status":"affected"}]}],"references":["https://github.com/PCSX2/pcsx2/security/advisories/GHSA-69wg-97fx-8j5w","https://github.com/PCSX2/pcsx2/commit/0b73eabd9ac19a5e290e7bee48d15be24e7b7d1b","https://github.com/PCSX2/pcsx2/releases/tag/v2.5.378"],"weaknesses":["CWE-125"],"ingestedAt":"2026-10-29T20:09:56.034Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/67xxx/CVE-2025-67749.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-67749","state":"PUBLISHED","datePublished":"2025-12-12T22:24:57.520Z","dateUpdated":"2025-12-15T14:59:28.999Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-12-11T20:30:54.927Z"},"containers":{"cna":{"title":"PCSX2 has an Out-of-bounds Read due to unchecked offset and size passed to memcpy","descriptions":[{"lang":"en","value":"PCSX2 is a free and open-source PlayStation 2 (PS2) emulator.
