Description
In the Linux kernel, the following vulnerability has been resolved:
bus: mhi: host: Range check CHDBOFF and ERDBOFF
If the value read from the CHDBOFF and ERDBOFF registers is outside the
range of the MHI register space then an invalid address might be computed
which later causes a kernel panic. Range check the read value to prevent
a crash due to bad data from the device.
