Hi, sashiko noted a sense buffer overflow on the io_uring path: Link: https://lore.kernel.org/linux-scsi/[email protected]/ Agreed. Completion copies scmd->sense_len without capping to max_response_len. Setting sense_len at submit does not help; the midlayer overwrites it with the real sense length. I will add a fix as 3/3 in v4 (store max_response_len in the PDU and cap the copy like the ioctl path). Thanks, Yang Xiuwei
