Adjacent code execution via S0 decryption overflow
Published Jun 21, 2023 · Updated Dec 6, 2024
Stack buffer overflow in S0 decryption in Silicon Labs Z/IP Gateway 7.18.01 and earlier allows remote attackers to execute arbitrary code. The S0 decryption path processes attacker-controlled Z-Wave frames into a fixed-size stack buffer without enforcing the buffer boundary. An attack requires no authentication or user interaction, but the attacker must be within Z-Wave radio range; successful exploitation grants code execution in the gateway process.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
