CVE-2018-10021: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.5% chance of exploitation in the next 30 days.

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

Affected products

• Linux Linux Kernel: before 4.16 (fixed in 4.16)
