Project Zero, Google's zero-day bug-hunting team, discovered and reported 18 zero-day vulnerabilities in Samsung’s Exynos chipsets used in mobile devices, wearables, and cars.

The Exynos modem security flaws were reported between late 2022 and early 2023. Four of the eighteen zero-days were identified as the most serious, enabling remote code execution from the Internet to the baseband.
