Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 4.15.9

Description: The issue is related to the Serial Attached SCSI (SAS) implementation in the Linux kernel, which mishandles a mutex within libsas. This allows local users to cause a denial of service (deadlock) by triggering certain error-handling code.
