AI-suggested

Users and administrators should update Blender to version 4.5.15 or later, or 5.2.3 or later, where this vulnerability is fixed. No other mitigations are indicated or required as the fix is available.

Description

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.
