CVE-2026-48706: Fixed Size Buffer Reallocation Bypass
A dynamic length check correctly identifies that the remaining buffer is smaller than the required size, but triggers a flush/reallocation method without passing the required size. If the reallocation uses a predefined fixed size chunk, memory overrun can occur when formatting the string. Ensure that the computed required size is propagated.
