CVE-2025-56361: n/a
A reachable assertion vulnerability exists in the Matter SDK (connectedhomeip) 1.3 thru 1.4, specifically within the Level Control cluster's server tick logic (`emberAfLevelControlClusterServerTickCallback`). When a MoveToLevel command is executed and followed by a conflicting write to the OperationMode attribute (in the Pump Configuration and Control cluster), an invariant check (`minLevel < currentLevel`) fails and causes the device to abort. This leads to a denial of service condition. The issue is confirmed in SDK versions 1.3 and 1.4 (commit ab3d5ae), and is triggered remotely without authentication.
AI Analysis
Technical Summary
This vulnerability exists in the Matter SDK (connectedhomeip) versions 1.3 and 1.4 within the Level Control cluster's server tick callback function. When a MoveToLevel command is executed and then a conflicting write to the OperationMode attribute in the Pump Configuration and Control cluster occurs, an invariant check (minLevel < currentLevel) fails. This assertion failure causes the device to abort, leading to a denial of service. The issue is remotely triggerable without requiring authentication. No patch or official remediation has been documented as of the published date.
Potential Impact
Successful exploitation causes the device to abort due to a failed invariant check, resulting in a denial of service condition. This can disrupt normal device operation remotely without authentication, potentially impacting device availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider limiting exposure of affected devices to untrusted networks to reduce the risk of remote exploitation.
