In the Linux kernel, the following vulnerability has been resolved:
scsi: mpt3sas: Fix kernel panic during drive powercycle test
While looping over shost's sdev list it is possible that one of the drives is getting removed and its sas_target object is freed but its sdev object remains intact.
Consequently, a kernel panic can occur while the driver is trying to access the sasaddress field of sastarget object without also checking the sas_target object for NULL.
