private_data_len is defined as a u8. If the user specifies a large private_data size (> 220 bytes), we will calculate a total length that exceeds 255, resulting in private_data_len wrapping back to 0. This can lead to overwriting random kernel memory. Avoid this by verifying that the resulting size fits into a u8. Reported-by: B.
