{"id":"UBUNTU-CVE-2025-67749","details":"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.","modified":"2026-05-20T16:23:42.333578196Z","published":"2025-12-12T23:15:00Z","upstream":["CVE-2025-67749"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-67749"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-67749"},{"type":"REPORT","url":"https://github.com/PCSX2/pcsx2/security/advisories/GHSA-69wg-97fx-8j5w"},{"type":"REPORT","url":"https://github.com/PCSX2/pcsx2/pull/13693"},{"type":"REPORT","url":"https://github.com/PCSX2/pcsx2/commit/0b73eabd9ac19a5e290e7bee48d15be24e7b7d1b"},{"type":"REPORT","url":"https://github.com/PCSX2/pcsx2/releases/tag/v2.5.378"}],"affected":[{"package":{"name":"pcsx2","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/pcsx2?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.1+dfsg-1build1","1.3.1-1094-gf062b0f+dfsg-1","1.3.1-1094-gf062b0f+dfsg-1build1","1.4.0+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"pcsx2","binary_version":"1.4.0+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-67749.json"}},{"package":{"name":"pcsx2","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/pcsx2?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.0+dfsg-2"],"ecosystem_specific":{"binaries":[{"binary_name":"pcsx2","binary_version":"1.4.0+dfsg-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-67749.json"}},{"package":{"name":"pcsx2","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/pcsx2?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.5.0~gfc1d9aef0+dfsg-1","1.5.0~gfc1d9aef0+dfsg-1ubuntu1","1.5.0~gfc1d9aef0+dfsg-2"],"ecosystem_specific":{"binaries":[{"binary_name":"pcsx2","binary_version":"1.5.0~gfc1d9aef0+dfsg-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-67749.json"}},{"package":{"name":"pcsx2","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/pcsx2?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.0+dfsg-1","1.6.0+dfsg-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.6.0+dfsg-1build1","binary_name":"pcsx2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-67749.json"}},{"package":{"name":"pcsx2","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/pcsx2?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.0+dfsg-2build1","1.6.0+dfsg-2ubuntu1","1.6.0+dfsg-2ubuntu3"],"ecosystem_specific":{"binaries":[{"binary_name":"pcsx2","binary_version":"1.6.0+dfsg-2ubuntu3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-67749.json"}},{"package":{"name":"pcsx2","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/pcsx2?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.0+dfsg-3"],"ecosystem_specific":{"binaries":[{"binary_name":"pcsx2","binary_version":"1.6.0+dfsg-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-67749.json"}},{"package":{"name":"pcsx2","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/pcsx2?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.0+dfsg-3","1.6.0+dfsg-3.1","2.4.0+dfsg-2","2.6.3+dfsg-1","2.6.3+dfsg-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"pcsx2","binary_version":"2.6.3+dfsg-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-67749.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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"},{"type":"Ubuntu","score":"medium"}]}
