Service interruption via malformed NWK/APS packet
Published Jan 28, 2025 · Updated Feb 18, 2025
Buffer overflow in Silicon Laboratories Simplicity SDK before 2024.12.0 allows physically proximate attackers to trigger an assert. The Ember ZNet NWK/APS packet-processing path copies data from a malformed packet beyond the destination buffer bounds, causing the stack assertion. No privileges or user interaction are required, but the attacker must be within adjacent-network range; the documented consequence is a service interruption rather than data access or modification.

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.
