What is CVE-2022-24611?

A Denial of Service vulnerability exists within the Z-Wave S0 NonceGet protocol utilized by Silicon Labs' Z-Wave 500 series. Local attackers can exploit this flaw by sending specially crafted S0 NonceGet packets, which can lead to interruptions in the S0/S2 protected Z-Wave networks. This vulnerability makes it possible for an attacker to effectively block network communications by utilizing included but not properly addressed NodeIDs, causing significant disruption to devices relying on this protocol. Awareness and timely software updates are essential to mitigate potential risks.
