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

    scsi: smartpqi: Use is_kdump_kernel() to check for kdump

    The smartpqi driver checks the reset_devices variable to determine
    whether special adjustments need to be made for kdump. This has the
    effect that after a regular kexec reboot, some driver parameters such as
    max_transfer_size are much lower than usual. More importantly, kexec
    reboot tests have revealed memory corruption caused by the driver log
    being written to system memory after a kexec.

    Fix this by testing is_kdump_kernel() rather than reset_devices where
    appropriate.
