CVE-2021-47188
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…
Does this matter?
Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.
