Summary
The Z-Wave SDK, a software development kit used to build Z-Wave wireless smart home devices, is affected by this flaw in its NCP SPI handler. A specially crafted malformed command sent over the SPI interface can cause the software to read memory outside its intended bounds, potentially exposing sensitive information.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
