Google’s security research unit is sounding the alarm on a set of vulnerabilities it found in certain Samsung chips included in dozens of Android models, wearables and vehicles, fearing the flaws could be soon discovered and exploited.

In a blog post, Google’s Project Zero head Tim Willis said the in-house security researchers found and reported 18 zero-day vulnerabilities in Exynos modems produced by Samsung over the past few months, including four top-severity flaws that could compromise affected devices “silently and remotely” over the cellular network.
