Exynos Vulnerabilities Found, Pixel Phones in Trouble

Yesterday, Google’s Challenge Zero detailed a number of (as in a complete of eighteen) web to Baseband Distant Code Execution Vulnerabilities in Samsung-made Exynos Modems. These modems might be present in units such because the Pixel 6 sequence, Pixel 7 sequence, Galaxy S22 sequence, and lots extra.

In layman’s, for these of us who aren’t safety specialists, essentially the most vital of the vulnerabilities would enable a talented attacker to create an exploit and compromise an affected telephone just by realizing a sufferer’s telephone quantity. 4 of the found vulnerabilities are so unhealthy that Challenge Zero even made a coverage exception with regard to its disclosure course of. It’s that unhealthy apparently.

Gadgets Probably Affected

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

So we’ve established that there’s a problem. The promising information is, the individuals who have to know and start correcting these points are conscious and fixes are already on the way in which. For instance, the March safety patch for Pixel telephones comprises a repair for one of many vulnerabilities. Within the meantime, Google’s Challenge Zero recommends that you just keep away from utilizing WiFi Calling or VoLTE (Voice-Over-LTE) by bodily going into your machine settings and disabling them.

Till safety updates can be found, customers who want to defend themselves from the baseband distant code execution vulnerabilities in Samsung’s Exynos chipsets can flip off Wi-Fi calling and Voice-over-LTE (VoLTE) of their machine settings. Turning off these settings will take away the exploitation threat of those vulnerabilities.

The speculation has been tossed round that these vulnerabilities is what’s retaining the Pixel 6 lineup from receiving the newest safety patch and Function Drop. That appears very believable at this level.

We’ll hold you posted as we study extra. If this information impacts you, I additionally suggest testing Challenge Zero’s put up on the scenario by following the hyperlink beneath.
