CVE-2018-10021
Published: 11 April 2018
** DISPUTED ** drivers/scsi/libsas/sas_scsi_host.c in the Linux kernel before 4.16 allows local users to cause a denial of service (ata qc leak) by triggering certain failure conditions. NOTE: a third party disputes the relevance of this report because the failure can only occur for physically proximate attackers who unplug SAS Host Bus Adapter cables.
From the Ubuntu Security Team
It was discovered that a memory leak existed in the Serial Attached SCSI (SAS) implementation in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (memory exhaustion).
