{"id":"UBUNTU-CVE-2026-60103","details":"Blender 3.0.0 through 5.1.2 contains an out-of-bounds read vulnerability that allows attackers to trigger a crash or read adjacent heap memory by supplying a crafted .blend file with a malicious signed short member_index value in the SDNA block. The member_index field is used as an array index into the sdna-\u003emembers[] array in sdna_expand_names() without bounds validation, allowing any value outside the allocated range to produce an invalid pointer subsequently passed to strlen(), resulting in a SIGSEGV crash or unintended heap memory disclosure.","modified":"2026-07-15T19:47:53.724866868Z","published":"2026-07-13T18:16:00Z","upstream":["CVE-2026-60103"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-60103"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-60103"},{"type":"REPORT","url":"https://projects.blender.org/blender/blender/pulls/161273"}],"affected":[{"package":{"name":"blender","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/blender?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.74+dfsg0-4build2","2.75.a+dfsg0-2ubuntu2","2.75.a+dfsg0-2ubuntu3","2.76.b+dfsg0-3","2.76.b+dfsg0-3build1"],"ecosystem_specific":{"binaries":[{"binary_name":"blender","binary_version":"2.76.b+dfsg0-3build1"},{"binary_version":"2.76.b+dfsg0-3build1","binary_name":"blender-data"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60103.json"}},{"package":{"name":"blender","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/blender?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.78.c+dfsg0-2build1","2.79+dfsg0-2build1","2.79+dfsg0-3","2.79+dfsg0-3build1","2.79.b+dfsg0-1","2.79.b+dfsg0-1ubuntu1.18.04.1"],"ecosystem_specific":{"binaries":[{"binary_name":"blender","binary_version":"2.79.b+dfsg0-1ubuntu1.18.04.1"},{"binary_name":"blender-data","binary_version":"2.79.b+dfsg0-1ubuntu1.18.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60103.json"}},{"package":{"name":"blender","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/blender?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.80+dfsg-3","2.80+dfsg-3build1","2.80+dfsg-4","2.81.a+dfsg-5build3","2.82+dfsg-1","2.82+dfsg-1build1","2.82.a+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"blender","binary_version":"2.82.a+dfsg-1"},{"binary_name":"blender-data","binary_version":"2.82.a+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60103.json"}},{"package":{"name":"blender","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/blender?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.93.3+dfsg-3","2.93.5+dfsg-1","2.93.5+dfsg-1build1","3.0.1+dfsg-7"],"ecosystem_specific":{"binaries":[{"binary_name":"blender","binary_version":"3.0.1+dfsg-7"},{"binary_version":"3.0.1+dfsg-7","binary_name":"blender-data"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60103.json"}},{"package":{"name":"blender","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/blender?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.6.2+dfsg-2ubuntu1","3.6.2+dfsg-2ubuntu2","4.0.2+dfsg-1ubuntu1","4.0.2+dfsg-1ubuntu2","4.0.2+dfsg-1ubuntu4","4.0.2+dfsg-1ubuntu6","4.0.2+dfsg-1ubuntu7","4.0.2+dfsg-1ubuntu8"],"ecosystem_specific":{"binaries":[{"binary_name":"blender","binary_version":"4.0.2+dfsg-1ubuntu8"},{"binary_name":"blender-data","binary_version":"4.0.2+dfsg-1ubuntu8"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60103.json"}},{"package":{"name":"blender","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/blender?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.3.2+dfsg-2ubuntu2","5.0.1+dfsg-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"blender","binary_version":"5.0.1+dfsg-1ubuntu1"},{"binary_name":"blender-data","binary_version":"5.0.1+dfsg-1ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60103.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
