Summary

Blender 3.0.0 through 5.1.2 has an out-of-bounds read vulnerability via a crafted .blend file with a malicious member_index in the SDNA block. Missing bounds validation causes a crash (SIGSEGV) or heap memory disclosure.

Risk Assessment

An attacker can remotely crash the application or leak sensitive heap memory, threatening system stability and data confidentiality.

Recommendation

Upgrade Blender to version 5.1.3 or later, which includes a fix for array index validation in sdna_expand_names().

Original NVD description (English source)

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.
