CVE-2025-56364
HighCVSS 7.5Exploitation Probability (EPSS)
Low risk25th percentile - higher than 25% of all known CVEs
Summary
A use of uninitialized value vulnerability exists in the Matter SDK (connectedhomeip) before version 1.4.0. The `GetDestinationGroupId().Value()` method is called without checking if a value exists, leading to a crash when an InvokeCommand is sent without initializing the destination group ID.
Risk Assessment
An attacker can cause a denial of service (DoS) by sending a crafted InvokeCommand request, resulting in application crash (SIGABRT) and potential disruption of Matter-based IoT devices.
Recommendation
Immediately update the Matter SDK to version 1.4.0 or later, which includes a fix adding a .HasValue() check before accessing the value.
Other vulnerabilities in Matter SDK
See all- CVE-2025-56365High
A reachable assertion vulnerability exists in the Matter SDK (connectedhomeip) before version 1.4.0, in the interaction model command processing logic. Sending an InvokeCommandRequest to a nonexistent endpoint and cluster (e.g., 0x34) causes the code to incorrectly treat the endpoint as valid due to missing checks in CodegenDataModelProvider::Invoke, leading to a VerifyOrDie failure in ProcessCommandDataIB and a crash (SIGABRT). The issue has been acknowledged and fixed in a later revision (PR #37207).
- CVE-2025-56363High
A null pointer dereference vulnerability exists in the Matter SDK (connectedhomeip) before version 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).
- CVE-2025-56362High
A reachable assertion vulnerability in Matter SDK (connectedhomeip) before 1.4.2 allows remote denial of service by sending a MoveToLevel command followed by writing OperationMode=2 in the Pump Configuration and Control cluster, causing a server crash.
- CVE-2025-56361High
A reachable assertion vulnerability in Matter SDK versions 1.3 and 1.4 causes device abort after a MoveToLevel command and conflicting write to the OperationMode attribute. The bug in Level Control cluster server tick logic leads to denial of service (DoS).
Original NVD description (English source)
A use of uninitialized value vulnerability exists in the Matter SDK (connectedhomeip) before 1.4.0, where the `GetDestinationGroupId().Value()` method is called without first checking whether a value exists. This leads to a crash when an InvokeCommand is sent without initializing the destination group ID. The issue affects all versions before commit 0360cc3 (Dec 5, 2024) and leads to denial of service through SIGABRT. It is fixed by adding a .HasValue() check before access.
