Title
Authenticated Denial-of-Service in Zigbee GetGroupMembership Handling
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.

Title
Out-of-bounds write in Zigbee Simple_Desc_req handling
Summary
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.

Title
Buffer overflow in Bluetooth Mesh SDK when handling extended advertisements
Summary
In Bluetooth Mesh SDK 6.1.4 and earlier, malformed extended advertisements can trigger out-of-bounds writes leading to stack corruption and remote code execution. These messages must come from a device that has already joined the network. Only provisioners supporting extended advertisements may be impacted.

Title
Out-of-bounds write in Zigbee Simple_Desc_req handling
Summary
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.

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.

Title
Weak entropy initialization in Silicon Labs Matter SiWx917 TinyCrypt path
Summary
A bug in the entropy initialization for SiWx917 causes the DRBG to use a predictable seed. As such, all random numbers generated in the Matter code use the same stream of numbers. This vulnerability was discovered after the impacted repository was already deprecated.
