CVE-2020-10137

Z-Wave devices based on Silicon Labs 700 series chipsets using S2 do not adequately authenticate or encrypt FIND_NODE_IN_RANGE frames, allowing a remote, unauthenticated attacker to inject a FIND_NODE_IN_RANGE frame with an invalid random payload, denying service by blocking the processing of upcoming events.
