CVE-2026-106432 Heap buffer overflow via 32-bit string-length truncation in MongoDB PHP Driver

The BSON encoder in the MongoDB PHP Driver converts a string length to a 32-bit value without validation. When an affected application encodes a string near 4 GiB, the allocation size can wrap while the copy operation uses the original length. The resulting heap buffer overflow can corrupt proces...
