Vulnerability from github – Published: 2025-07-25 18:30 – Updated: 2025-07-25 18:30

Details

In high traffic environments, a Silicon Labs OpenThread RCP (see impacted versions) fails to clear the SPI transmit buffer and may send a corrupt packet over SPI to its host, causing the host to reset the RCP which results in a denial of service.

Severity ?

5.3 (Medium)
