## Overview

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

scsi: qla2xxx: Fix premature hw access after PCI error

After a recoverable PCI error has been detected and recovered, qla driver
needs to check to see if the error condition still persist and/or wait
for the OS to give the resume signal.
