Samsung has released fixes, but it's up to the carriers & manufacturers other than Samsung to push them out to your phones & any other devices -- while the article lists: S22, M33, M13, M12, A71, A53, A33, A21, A13, A12 and A04 series phones, I couldn't find a list of vehicles using the effected auto chipset doing a quick Google.
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.
These Internet-to-baseband remote code execution (RCE) bugs (including CVE-2023-24033 and three others still waiting for a CVE-ID) allow attackers to compromise vulnerable devices remotely and without any user interaction.
However, until patches are available, users can thwart baseband RCE exploitation attempts targeting Samsung's Exynos chipsets in their device by disabling Wi-Fi calling and Voice-over-LTE (VoLTE) to remove the attack vector.Samsung also confirmed Project Zero's workaround, saying that "users can disable WiFi calling and VoLTE to mitigate the impact of this vulnerability."
