Short explanation
CVE-2026-119722 affects Blender before 4.5.15 and 5.x before 5.2.3 in the read_struct() function. It contains a heap out-of-bounds access vulnerability that skips size validation when an SDNA struct layout compares equal. A crafted .blend file can cause field reads, writes, and pointer dereferences to overrun heap memory, leading to crashes or code execution.
This vulnerability allows attackers to potentially achieve code execution or cause application crashes via a crafted .blend file with high impact. Applying updates is critical for users running affected versions.
What should be done?
- Update Blender to version 4.5.15, 5.2.3, or later.
- Avoid opening .blend files from untrusted sources.
- Follow vendor advisories and patch instructions.
Chain of evidence and sources
Blender sürümleri 4.5.15 öncesi ve 5.x serisinde 5.2.3 öncesi read_struct() içinde yığın sınır dışı erişim zafiyeti barındırır.
Özel olarak hazırlanmış .blend dosyaları, kısa bloklar yoluyla yığın belleğin aşılmasına ve kod yürütülmesine sebep olabilir.
Show the technical text from the sources
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.
