CyberRota Analysis
AI-GeneratedA null pointer dereference vulnerability in the Matter SDK prior to version 1.4.0 affects multiple clusters, including Channel, Account Login, and TargetNavigator, due to inadequate validation of the delegate pointer in the ReadRevisionAttribute function. This flaw allows remote unauthenticated attackers to exploit the vulnerability by sending specially crafted read requests, leading to a denial of service through device crashes. Organizations utilizing the Matter SDK should prioritize patching to mitigate this high-severity risk.

Original NVD Description
A null pointer dereference vulnerability exists in the Matter SDK (connectedhomeip) before 1.4.0, affecting the ReadRevisionAttribute function used in multiple clusters (Channel, Account Login, TargetNavigator, etc.). The function lacks proper validation of the delegate pointer before dereferencing. A remote unauthenticated attacker can exploit this issue by sending a crafted read request, causing the device to crash (denial of service). This issue has been confirmed in SDK version v1.4 (commit ab3d5ae).
