In the Linux kernel, the following vulnerability has been resolved:
mips: bmips: BCM6358: make sure CBR is correctly set
It was discovered that some device have CBR address set to 0 causing kernel panic when archsyncdmaforcpu_all is called.
This was notice in situation where the system is booted from TP1 and BMIPSGETCBR() returns 0 instead of a valid address and !!(readc0brcmcmtlocal() & (1 << 31)); not failing.
The current check whether RAC flush should be disabled or not are not enough hence lets check if CBR is a valid address or not.
