CVE-2025-56362
HighCVSS 7.5Exploitation Probability (EPSS)
Low risk25th percentile - higher than 25% of all known CVEs
Summary
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.
Risk Assessment
An unauthenticated attacker can remotely crash the server, leading to denial of service and potentially affecting the availability of IoT systems.
Recommendation
Immediately update Matter SDK to version 1.4.2 or later, which includes the fix for this vulnerability.
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-2025-56364High
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.
- 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-2025-56361High
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 reachable assertion vulnerability exists in the Matter SDK (connectedhomeip) before 1.4.2, specifically within the Level Control cluster's periodic server tick logic. When a MoveToLevel command is sent and immediately followed by a write of OperationMode=2 (in the Pump Configuration and Control cluster), the server tick function violates the assertion `currentLevel < maxLevel`, resulting in a crash. This can be exploited remotely without authentication to cause denial of service. Affected versions include 1.3 and 1.4 (commit ab3d5ae).
