Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Integer Overflow: Deserializing malformed indexes with extremely large 'ntotal' values or code sizes causes multiplication overflows during size calculation. This leads to under-allocated buffers and subsequent out-of-bounds heap writes during memcpy.
Memory Corruption: Inconsistent or unvalidated structural parameters, such as mismatched dimensions in VectorTransform/IndexPreTransform chains or out-of-range SVSStorageKind enum values, trigger undefined memory layouts and severe memory corruption during index deserialization.
Integer Overflow: Large query parameters passed to IndexRefine search functions result in integer overflows when calculating buffer allocations for search results, leading to undersized heap buffers and heap buffer overflows.
