kernel: NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery
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.
A NULL pointer dereference flaw was found in the Linux kernel’s SCSI disk subsystem. A local user could use this flaw to crash the system, causing a denial of service.
Mitigation: To mitigate this issue, prevent module libsas from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
