Summary
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->members[] 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.
