Arm has informed us that among their affected CPU cores, Cortex A9, A15, A57, Cortex R7 are used in our R-Car products ( No impact to Cortex A7 and A53). ARM has released their security patch, we are working with Arm and other companies on this issue.
The majority of Renesas CPUs are not impacted by any variation of the side-channel speculation mechanism.
The common usage model which Renesas proprietary CPUs use is closed environments where applications or processes are strictly controlles and hence not exploitable.
