PYSEC-2026-3388 Tornado has out-of-bounds memory access via C extension

Summary Tornado's optional native extension tornado.speedups implements websocketmask without validating that the mask argument is exactly four bytes long. The C function reads four bytes from mask unconditionally, even when Python passes a shorter byte string. This can read beyond the provided...
