CWE
- CWE-130 - Improper Handling of Length Parameter Inconsistency, CWE-787: Out-of-bounds Write
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.

CWE
- CWE-336 - Same Seed in Pseudo-Random Number Generator (PRNG)
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.

CWE
- CWE-125 - Out-of-bounds Read
Summary
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.

Summary
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.

- CWE-125 - Out-of-bounds Read, CWE-130: Improper Handling of Length Parameter Inconsistency
Summary
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.

- CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Summary
Silicon Labs Gecko OS DNS Response Processing Infinite Loop Denial-of-Service Vulnerability. This vulnerability allows network-adjacent attackers to create a denial-of-service condition on affected installations of Silicon Labs Gecko OS. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the processing of DNS responses. The issue results from a logic error that can lead to an infinite loop. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-23392.

CWE
- CWE-121 - Stack-based Buffer Overflow
Summary
Silicon Labs Gecko OS HTTP Request Handling Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Silicon Labs Gecko OS. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of HTTP requests. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-23245.

Summary
This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of Silicon Labs Gecko OS. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the debug interface. The issue results from the lack of proper validation of a user-supplied string before using it as a format specifier. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the device.

Summary
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Silicon Labs Gecko OS. Authentication is not required to exploit this vulnerability.Â
The specific flaw exists within the handling of HTTP GET requests. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device.
