On a PS5 (firmware 13.60) a null name returns INVALID_ARGUMENT first, then a user id the console does not know returns 0x80960105 whatever the buffer, and a buffer shorter than 17 bytes is zeroed before BUFFER_TOO_SHORT is returned. Here an unknown user returned INVALID_ARGUMENT and a short buffer was left untouched. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
