CVE-2026-60103 Details
Description
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.
A vulnerability allowing out-of-bounds read has been identified in Blender versions 3.0.0 through 5.1.2. This issue arises when a crafted .blend file is used, specifically one that contains a malicious signed short member_index value in the SDNA block. The vulnerability occurs because the member_index is applied as an array index in the sdna->members[] array within the sdna_expand_names() function, without proper bounds validation. This oversight allows values outside the allocated range to generate invalid pointers, which are then passed to the strlen() function. The result is a SIGSEGV crash or unintended disclosure of adjacent heap memory.
Users can update to the latest version of Blender, where this vulnerability has been addressed.
