Doc Text:
A flaw was found in Blender. A remote attacker could exploit an out-of-bounds read vulnerability by providing a specially crafted .blend file. This vulnerability occurs when the application processes a malicious member_index value without proper validation, leading to an attempt to access memory outside of its allocated boundaries. Successful exploitation can result in a denial of service, causing the application to crash, or potentially lead to the disclosure of sensitive information from the system's memory.

Description OSIDB Bzimport 2026-07-13 18:01:47 UTC 
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.
