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.

How can this vulnerability impact me? :

This vulnerability can cause the Linux kernel to crash unexpectedly (kernel panic) if a device provides bad data in the CHDBOFF or ERDBOFF registers. Such crashes can lead to system instability, downtime, and potential loss of data or service availability.


Can you explain this vulnerability to me?

This vulnerability occurs in the Linux kernel's MHI host driver where the values read from the CHDBOFF and ERDBOFF registers are not properly range-checked. If these values are outside the valid range of the MHI register space, it can lead to the calculation of an invalid address, which subsequently causes a kernel panic (system crash). The fix involves adding range checks to these register values to prevent crashes caused by bad data from the device.
