Authenticated memory disclosure via integer underflow
Published Jan 5, 2026 · Updated Jan 5, 2026
Integer underflow in Silicon Labs Z-Wave Protocol Controller before 1.7.1 allows remote authenticated users to read out-of-bounds memory. Silicon Labs has not published the affected parser, function, input field, or arithmetic operation that underflows before the read. Network access and low privileges are required; the published impact is limited to reading vulnerable-process memory, with no integrity or availability effect.

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.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
