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

scsi: ufs: core: Fix possible NULL pointer dereference in ufshcd_add_command_trace()

The kernel log indicates a crash in ufshcd_add_command_trace, due to a NULL pointer dereference when accessing hwq->id. This can happen if ufshcd_mcq_req_to_hwq() returns NULL.

This patch adds a NULL check for hwq before accessing its id field to prevent a kernel crash.
