It was found that the Linux kernel is vulnerable to an out-of-bounds buffer write due to incorrect bounds check in drivers/amba/bus.c:driver_override_store() function. This can lead to a memory corruption, a system panic and to a denial-of-service. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
