Gadgets that make the most of Samsung Exynos modems could also be a straightforward goal for hackers. In a brand new report, Google’s Challenge Zero crew recognized 18 zero-day vulnerabilities in latest Exynos modems. Google suggests disabling Wi-Fi calling and VoLTE on affected gadgets, although most customers can’t disable these settings.
Solely 4 of the vulnerabilities recognized by Challenge Zero are of fast concern. In accordance with Challenge Zero, these vulnerabilities might allow internet-to-baseband distant code execution. Whereas the main points are a bit unclear, Challenge Zero claims that hackers can exploit these vulnerabilities utilizing solely a sufferer’s cellphone quantity. (The opposite 14 vulnerabilities require a “malicious cellular community operator or an attacker with native entry to the gadget.”)
Challenge Zero first reported these vulnerabilities in late 2022. Google included a patch within the Pixel 7’s March replace (which you must set up in case you haven’t already), however as Challenge Zero’s Maddie Stone notes, most gadgets are nonetheless unpatched.

Sadly, it’s onerous to determine all of the gadgets which may be affected by this exploit. Challenge Zero put collectively a rudimentary checklist utilizing public data, although I’m unsure that it is a full checklist (I think that smartwatches with new Exynos mobile modems could also be affected as effectively):

Cellular gadgets from Samsung, together with these within the S22, M33, M13, M12, A71, A53, A33, A21s, A13, A12 and A04 collection.
Cellular gadgets from Vivo, together with these within the S16, S15, S6, X70, X60 and X30 collection.
The Pixel 6 and Pixel 7 collection of gadgets from Google.
Any automobiles that use the Exynos Auto T5123 chipset.

In accordance with Samsung, the Exynos Modem 5123, Exynos Modem 5300, Exynos 980, Exynos 1080, and Exynos Auto T5123 are affected by these vulnerabilities.
Challenge Zero normally publishes detailed data on zero-day exploits. However because of the severity of those vulnerabilities, it’s holding again some data. For what it’s price, solely one of many 4 main vulnerabilities (CVE-2023-24033) has been assigned a CVE.

In its weblog publish, Challenge Zero means that customers disable Wi-Fi calling and VoLTE on affected gadgets (open Settings, go to “Community and Web,” and choose “SIM”). Disabling these settings will stop cellphone calls from being made or obtained on most provider networks. And, sadly, some carriers don’t allow you to alter these settings.
My recommendation is to put in the newest replace out there to your cellphone. Relying on if you learn this text, the March Android patch could also be out there to you (thereby resolving this subject). If you happen to’re a high-risk goal, chances are you’ll need to disable Wi-Fi calling and VoLTE, although this isn’t a sensible choice for many customers.
