The researchers looked into chips made by Broadcom, Silicon Labs, and Cypress, which are found inside billions of electronic devices.Īll flaws have been responsibly reported to the chip vendors, and some have released security updates where possible. In other cases, mitigating security issues such as packet timing and metadata flaws would result in severe packet coordination performance drops.
Some of the above flaws can only be fixed by a new hardware revision, so firmware updates cannot patch all the identified security problems.įor example, flaws that rely on physical memory sharing cannot be addressed by security updates of any kind.
