{"id":"UBUNTU-CVE-2026-110735","details":"Godot Engine through 4.7.2 has a heap out-of-bounds write in the binary resource loader (core/io/resource_format_binary.cpp, ResourceLoaderBinary::get_unicode_string). A string length is read from the resource file into a signed 32-bit integer and compared against the destination buffer size with a signed comparison, which conditionally resizes the buffer. A negative length value skips the resize; the same value is then passed to the copy routine as an unsigned byte count, where it sign-extends to a huge value, copying file-controlled data far past the undersized heap allocation. The defect is reached when the product or an exported game loads a crafted binary resource file (.res). NOTE: the Supplier's position is that the research has identified \"no security issues\" because the required attacker access is outside of the current Godot Engine threat model.","modified":"2026-10-17T12:58:03.403737595Z","published":"2026-10-15T00:00:00Z","upstream":["CVE-2026-110735"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-110735"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-110735"},{"type":"REPORT","url":"https://axeghost.offprint.app/a/3mvs6zo4blo23-three-memory-safety-bugs-in-godots-untrusted-file-parsers"},{"type":"REPORT","url":"https://github.com/godotengine/godot/issues/123608"}],"affected":[{"package":{"name":"godot","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/godot?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.0.6-2build1","3.0.6-2build2","3.2-stable-2","3.2-stable-2ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"godot3","binary_version":"3.2-stable-2ubuntu0.1~esm1"},{"binary_name":"godot3-runner","binary_version":"3.2-stable-2ubuntu0.1~esm1"},{"binary_version":"3.2-stable-2ubuntu0.1~esm1","binary_name":"godot3-server"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110735.json"}},{"package":{"name":"godot","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/godot?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2.3-stable-1","3.2.3-stable-1build1","3.2.3-stable-1build2","3.2.3-stable-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"godot3","binary_version":"3.2.3-stable-1ubuntu0.1~esm1"},{"binary_name":"godot3-runner","binary_version":"3.2.3-stable-1ubuntu0.1~esm1"},{"binary_version":"3.2.3-stable-1ubuntu0.1~esm1","binary_name":"godot3-server"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110735.json"}},{"package":{"name":"godot","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/godot?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.5.2-stable-2","3.5.2-stable-2build1","3.5.2-stable-2build3","3.5.2-stable-2build4","3.5.2-stable-2ubuntu0.24.04.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.5.2-stable-2ubuntu0.24.04.1~esm1","binary_name":"godot3"},{"binary_version":"3.5.2-stable-2ubuntu0.24.04.1~esm1","binary_name":"godot3-runner"},{"binary_name":"godot3-server","binary_version":"3.5.2-stable-2ubuntu0.24.04.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110735.json"}},{"package":{"name":"godot","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/godot?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.6.3+ds-1","4.6.3+ds-2"],"ecosystem_specific":{"binaries":[{"binary_name":"godot","binary_version":"4.6.3+ds-2"},{"binary_name":"godot-template-debug","binary_version":"4.6.3+ds-2"},{"binary_name":"godot-template-release","binary_version":"4.6.3+ds-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110735.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
