Vendor / product: Blender — blender
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.
