In the Linux kernel, the following vulnerability has been resolved:
scsi: smartpqi: Use iskdumpkernel() to check for kdump
The smartpqi driver checks the resetdevices 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 maxtransfer_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 iskdumpkernel() rather than reset_devices where appropriate.
