Vulnerability Title
DoS caused due to wrong hash length returned for SHA2/224 algorithm
Source: CVE Program / CVE List V5
Vulnerability Description
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
