Subject: CVE Request: Linux kernel: arm64: unhandled el0 traps


Linux kernel built for the ARM64(CONFIG_ARM64) platform is vulnerable to a 
crash when the processor generates trap/esr, that is not handled gracefully, 
which leads to bad_mode(), wherein it'll die() or oops().

A user/program could use this flaw to crash the kernel resulting in DoS.

Upstream fixes:

Thank you.
