Official description

In the Linux kernel, the following vulnerability has been resolved: scsi: bsg: Pass reply_len to bsg_setup_queue() to fit UFS ARPMB replies bsg-lib allocates a 96-byte (SCSI_SENSE_BUFFERSIZE) reply buffer per job, but struct ufs_rpmb_reply is 104 bytes: a 40-byte struct ufs_bsg_reply followed by a 64-byte EHS. When an Advanced RPMB command returns an EHS, ufshcd_advanced_rpmb_req_handler() copies it right after the 40-byte header and writes 8 bytes past the end of the buffer. Let each BSG transport pass its reply buffer size to bsg_setup_queue() and have ufs_bsg request sizeof(struct ufs_rpmb_reply), so the full reply reaches user space. Other transports keep SCSI_SENSE_BUFFERSIZE.
