CVE-2019-19965

Priority
Description
In the Linux kernel through 5.4.6, there is a NULL pointer dereference in
drivers/scsi/libsas/sas_discover.c because of mishandling of port
disconnection during discovery, related to a PHY down race condition, aka
CID-f70267f379b5.
Ubuntu-Description
Gao Chuan discovered that the SAS Class driver in the Linux kernel
contained a race condition that could lead to a NULL pointer dereference. A
local attacker could possibly use this to cause a denial of service (system
crash).
