CVE-2026-48690: Cpp Integer Truncation Allocation
An allocation size calculation is stored in a 32-bit (or smaller) integer variable. This can cause an integer overflow or silent truncation (if `sizeof` or other 64-bit types are involved). A wraparound leads to allocating an unexpectedly small buffer, which can cause a heap-based buffer overflow when data is written to it. Ensure allocation sizes are typed
