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

scsi: ufs: core: Improve SCSI abort handling

The following has been observed on a test setup:

WARNING: CPU: 4 PID: 250 at drivers/scsi/ufs/ufshcd.c:2737 ufshcd_queuecommand+0x468/0x65c
Call trace:

That warning is triggered by the following statement:
