Google's security research team has warned about a number of vulnerabilities that they uncovered in certain Samsung processors used in Android phones, wearables, and automobiles. In a blog post, the director of Google's Project Zero revealed that his team discovered 18 zero-day vulnerabilities in Samsung's Exynos modems, including four critical holes that could surreptitiously infect afflicted devices through the cellular network. These flaws might allow attackers to intercept calls, texts, and other data without notifying the victim.
Phones from Samsung, including the S22, M33, M13, M12, A71, A53, A33, A21, A13, A12, and A04 series, as well as Vivo phones, including the S16, S15, S6, X70, X60, and X30 series, are also affected. Additionally, Google's own Pixel 6 and Pixel 7 series, as well as wearables and cars that use Samsung's Exynos W920 and Auto T5123 chips to connect to the cellular network, are among those affected. While Google's Pixel smartphones have already received March security upgrades to patch these vulnerabilities, updates for other susceptible devices will be determined by the vendor. Consumers may safeguard themselves by turning off Wi-Fi calling and Voice-over-LTE in their device settings.
