Vulnerability Title
scsi: ufs: core: bsg: Fix crash when arpmb command fails
Source: NVD (National Vulnerability Database)
Vulnerability Description
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.
