Threats affecting pkg:github/EmberZNet

CVE-2026-85079 is a stack-based buffer overflow vulnerability in Silicon Labs EmberZNet versions 9.1.1 and earlier. It occurs when a malformed Simple_Desc_req response is processed, leading to an out-of-bounds write. Exploitation requires the response to come from a device already joined to the network and the attacker must wait for a Simple_Desc_req before launching the attack. The vulnerability has a high severity with a CVSS 4.0 score of 7.5.

A stack-based buffer overflow vulnerability exists in Silicon Labs EmberZNet versions 9.1.1 and earlier. It is triggered by a malformed Publish Price Matrix command sent from a device that has already joined the network. This vulnerability affects only devices supporting the Price Cluster and can potentially lead to remote code execution.

CVE-2026-66282 is a vulnerability in Silicon Labs EmberZNet versions 9.1.1 and earlier. It involves uncontrolled recursion triggered by a malformed Publish Billing Period command, which causes a recursive function call without reaching its end condition. This issue affects only devices that have joined the network and support the Price Cluster. The vulnerability has a medium severity rating with a CVSS 4.0 score of 6.0.

CVE-2026-66281 is a vulnerability in Silicon Labs EmberZNet versions 9.1.1 and earlier where a malformed Discover Attributes command can cause an infinite loop due to an unreachable exit condition. This issue affects only devices that have already joined the network and support manufacturer-specific clusters.

A stack-based buffer overflow vulnerability exists in Silicon Labs EmberZNet versions 9.1.1 and earlier. This flaw is triggered by a malformed GetGroupMembership message sent from a device that has already joined the network and supports the Group Cluster. The vulnerability can cause an out-of-bounds write leading to a crash. No remote code execution path has been observed due to limited values being writable.

Improper bounds validation in the ZAP command parser of EmberZNet SDK versions 8.0.0 through 9.1.1 (inclusive) and before 7.5.2 (exclusive) may result in crashes or dynamic memory leakage. In order to exploit this vulnerability, an attacker would have to have the ability to send arbitrary messages on the network. The only known exploit of this vulnerability leaks a limited number of bytes from the stack. No denial-of-service, memory corruption, or remote code execution has been shown.

In EmberZNet v9.0.2 and earlier, a malformed GetProfileResponse message can trigger out-of-bounds reads while iterating interval entries and terminate the process. These messages must come from a device that has already joined the network, and no information leakage back to the sender was observed. Only devices supporting the Simple Metering cluster may be impacted.

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. Only devices supporting the Level Control cluster may be impacted.

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. Only devices supporting the Level Control cluster may be impacted.

In EmberZNet v9.0.2 and earlier, malformed ClearWeekdaySchedule messages can trigger out-of-bounds writes into Door Lock schedule state. The size and location of this data is limited. These messages must come from a device that has already joined the network. Only devices supporting the Door Lock cluster may be impacted.

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. These messages must come from a device that has already joined the network. Only devices supporting the IAS Zone cluster may be impacted.

In EmberZNet v9.0.2 and earlier, malformed or out-of-range Door Lock user identifiers can trigger out-of-bounds table reads and terminate the process. These messages must come from a device that has already joined the network, and no information leakage back to the sender was observed. Only devices supporting the Door Lock cluster may be impacted.

In EmberZNet v9.0.2 and earlier, malformed GetGroupMembership commands can trigger repeated reads past the end of the message payload and terminate the process. These messages must come from a device that has already joined the network, and no information leakage back to the sender was observed. Only devices supporting the Groups cluster may be impacted.

In EmberZNet v9.0.2 and earlier, malformed OTA requests can drive the OTA server parser into out-of-bounds reads. A limited amount of data from RAM is read back to the requester. The size and location of this data is limited. These requests must come from a device that has already joined the network. Only devices supporting the OTA Server cluster may be impacted.

In EmberZNet v9.0.2 and earlier, malformed Color Control messages can lead to asserts that terminate the process. These messages must come from a device that has already joined the network. Only devices supporting the Color Control cluster may be impacted.

In EmberZNet v9.0.2 and earlier, malformed Color Control messages can lead to asserts that terminate the process. These messages must come from a device that has already joined the network. Only devices supporting the Color Control cluster may be impacted.

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, and no information leakage back to the sender was observed.
