CVE-2026-6924 Weak entropy initialization in Silicon Labs Matter SiWx917 TinyCrypt path

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...
