Detail
Description
In the Linux kernel, the following vulnerability has been resolved:
scsi: megaraid_sas: Fix resource leak in case of probe failure
The driver doesn't clean up all the allocated resources properly when
scsi_add_host(), megasas_start_aen() function fails during the PCI device
probe.
Clean up all those resources.
