scsi: mpi3mr: Fix corrupt config pages PHY state is switched in sysfs
In the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Fix corrupt config pages PHY state is switched in sysfs The driver, through the SAS transport, exposes a sysfs interface to enable/disable PHYs in a controller/expander setup. When multiple PHYs are disabled and enabled in rapid succession, the persistent and current config pages related to SAS IO unit/SAS Expander pages could get corrupted. Use separate memory for each config request.
