HIGHCVSS 7.5/10EPSS 0.41%

Last modified

CVE-2024-8361 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. EPSS estimates a 0.41% chance of exploitation in the next 30 days.

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
