CVE-2024-8361: Silabs.com Wiseconnect SDK

High severity, CVSS 7.5. EPSS: 0.4% chance of exploitation in the next 30 days.

In SiWx91x devices, the SHA2/224 algorithm returns a hash of 256 bits instead of 224 bits. This incorrect hash length triggers a software assertion, which subsequently causes a Denial of Service (DoS). If a watchdog is implemented, device will restart after watch dog expires. If watchdog is not implemented, device can be recovered only after a hard reset
