CVE-2025-43385 is a heap-based buffer overflow in Apple’s Model I/O handling of USD content, specifically within the USD library’s importMeshes functionality. The flaw is caused by insufficient validation of the length of user-supplied data before it is copied into a heap-allocated buffer, resulting in an out-of-bounds memory access. Apple describes the issue as an out-of-bounds access addressed through improved bounds checking. Processing a maliciously crafted media file can trigger unexpected application termination or corrupt process memory. Third-party analysis indicates the memory corruption condition is exploitable for arbitrary code execution in the context of the affected process.
