CVE-2019-19965
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.
Does this matter?
Lower severity and a low EPSS score (0.65%). Track it; it rarely justifies an emergency change on its own.
