Low risk40th percentile - higher than 40% of all known CVEs
Summary
In EmberZNet 9.1.1 and earlier, a malformed GetGroupMembership message can result in an out-of-bounds write leading to a crash. A limited number of values can be written using this vulnerability, so no route to remote code execution was observed. These messages must come from a device that has already joined the network. Only devices supporting the Group Cluster are impacted.
Risk Assessment
An attacker in the network could cause a device crash (denial of service), disrupting Zigbee network operation.
Recommendation
Update EmberZNet to a version later than 9.1.1 and limit trust in devices that have joined the network.
Other vulnerabilities in EmberZNet
See all- CVE-2026-94502Critical
In EmberZNet 9.1.1 and earlier, a malformed Publish Price Matrix command can result in an out-of-bounds write potentially leading to remote code execution. These messages must come from a device that has already joined the network. Only devices supporting the Price Cluster are impacted.
- CVE-2026-85079Critical
In EmberZNet 9.1.1 and earlier, a malformed Simple_Desc_req response can result in an out-of-bounds write potentially leading to remote code execution. This response must come from a device that has already joined the network, and the attacker must wait for a Simple_Desc_req before the attack can be performed.
- CVE-2026-66282High
In EmberZNet 9.1.1 and earlier, a malformed Publish Billing Period command can result in a recursive function call that will never reach its end condition. These messages must come from a device that has already joined the network. Only devices supporting the Price Cluster are impacted.
- CVE-2026-66281High
In EmberZNet 9.1.1 and earlier, a malformed Discover Attributes command can result in a loop with unreachable exit condition (infinite loop). These messages must come from a device that has already joined the network. Only devices supporting manufacturer-specific clusters are impacted.
- CVE-2026-4526Medium
In EmberZNet v9.0.2 and earlier, malformed global ZCL messages can trigger out-of-bounds reads in framework parsing logic and terminate the process. These messages must come from a device that has already joined the network.
- CVE-2026-47154Medium
In EmberZNet v9.0.2 and earlier, a malformed GetProfileResponse message can trigger out-of-bounds reads while iterating interval entries, resulting in process termination. These messages must come from a device that has already joined the network.
- CVE-2026-47153Medium
In EmberZNet v9.0.2 and earlier, a malformed Level Control Step command can terminate the process through a divide-by-zero fault. This command must come from a device that has already joined the network.
- CVE-2026-47152Medium
In EmberZNet v9.0.2 and earlier, a malformed Level Control Move command can terminate the process through a divide-by-zero fault. This command must come from a device that has already joined the network.
- CVE-2026-47151High
In EmberZNet v9.0.2 and earlier, malformed ClearWeekdaySchedule messages can trigger out-of-bounds writes into Door Lock schedule state. Only devices that have already joined the network and support the Door Lock cluster may be impacted.
- CVE-2026-47150High
In EmberZNet v9.0.2 and earlier, malformed IAS Zone enrollment messages can trigger an out-of-bounds state-table write and terminate the process. The size and location of this write is limited.
