Technical description

In the Linux kernel, the following vulnerability has been resolved:

scsi: mpt3sas: Fix use after free in _scsih_expander_node_remove()

The function mpt3sas_transport_port_remove() called in

_scsih_expander_node_remove() frees the port field of the sas_expander

structure, leading to the following use-after-free splat from KASAN when

the ioc_info() call following that function is executed (e.g. when doing

rmmod of the driver module):
