In the Linux kernel, the following vulnerability has been resolved:

scsi: ufs: core: bsg: Fix crash when arpmb command fails

If the device doesn't support arpmb we'll crash due to copying user data in
bsg_transport_sg_io_fn().

In the case where ufs_bsg_exec_advanced_rpmb_req() returns an error, do not
set the job's reply_len.
