    CVE-2026-6924 (GCVE-0-2026-6924)

    Vulnerability from nvd – Published: 2026-07-23 21:05 – Updated: 2026-07-24 13:40
    VLAI
    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.
