{"id":"UBUNTU-CVE-2026-119722","details":"Blender before 4.5.15 and 5.x before 5.2.3 contains a heap out-of-bounds access vulnerability in read_struct() that skips size validation when a .blend file's SDNA struct layout compares equal. Attackers can supply a crafted .blend file with short blocks so field reads, writes, and pointer dereferences overrun heap memory, causing crashes or code execution.","modified":"2026-11-04T03:30:35.167802798Z","published":"2026-11-03T00:00:00Z","upstream":["CVE-2026-119722"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-119722"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-119722"},{"type":"REPORT","url":"https://projects.blender.org/blender/blender/pulls/164279"},{"type":"REPORT","url":"https://projects.blender.org/blender/blender/commit/c5d6faf04bf3f17efb6c404896ef0e7427784da5"},{"type":"REPORT","url":"https://projects.blender.org/blender/blender/commit/7de4986e74ed47f67e78eb4b76609bb6d1ae8a0e"},{"type":"REPORT","url":"https://projects.blender.org/blender/blender"},{"type":"REPORT","url":"https://projects.blender.org/blender/blender/commit/7de4986e74ed47f67e78eb4b76609bb6d1ae8a0e"},{"type":"REPORT","url":"https://projects.blender.org/blender/blender/commit/c5d6faf04bf3f17efb6c404896ef0e7427784da5"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/blender-before-4.5.15-and-5-x-before-5.2.3-heap-out-of-bounds-access-via-read-struct"}],"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_version":"2.76.b+dfsg0-3build1","binary_name":"blender"},{"binary_name":"blender-data","binary_version":"2.76.b+dfsg0-3build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119722.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_version":"2.79.b+dfsg0-1ubuntu1.18.04.1","binary_name":"blender"},{"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-2026-119722.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_version":"2.82.a+dfsg-1","binary_name":"blender"},{"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-2026-119722.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_name":"blender-data","binary_version":"3.0.1+dfsg-7"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119722.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_version":"4.0.2+dfsg-1ubuntu8","binary_name":"blender"},{"binary_version":"4.0.2+dfsg-1ubuntu8","binary_name":"blender-data"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119722.json"}},{"package":{"name":"blender","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/blender?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.1+dfsg-1ubuntu1","5.0.1+dfsg-1ubuntu3","5.0.1+dfsg-3build1","5.0.1+dfsg-5"],"ecosystem_specific":{"binaries":[{"binary_version":"5.0.1+dfsg-5","binary_name":"blender"},{"binary_name":"blender-data","binary_version":"5.0.1+dfsg-5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119722.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"],"ecosyste
