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 may be present in gadgets such because the Pixel 6 sequence, Pixel 7 sequence, Galaxy S22 sequence, and lots extra.
In layman’s, for these of us who should not safety specialists, essentially the most crucial of the vulnerabilities would permit a talented attacker to create an exploit and compromise an affected telephone just by figuring out a sufferer’s telephone quantity. 4 of the found vulnerabilities are so dangerous that Challenge Zero even made a coverage exception with regard to its disclosure course of. It’s that dangerous apparently.
Units Probably Affected

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

So we’ve established that there’s a difficulty. The promising information is, the individuals who have to know and start correcting these points are conscious and fixes are already on the best way. For instance, the March safety patch for Pixel telephones incorporates a repair for one of many vulnerabilities. Within the meantime, Google’s Challenge Zero recommends that you simply keep away from utilizing WiFi Calling or VoLTE (Voice-Over-LTE) by bodily going into your system settings and disabling them.
Till safety updates can be found, customers who want to shield 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 system settings. Turning off these settings will take away the exploitation danger of those vulnerabilities.
The idea has been tossed round that these vulnerabilities is what’s preserving the Pixel 6 lineup from receiving the most recent safety patch and Characteristic Drop. That appears very believable at this level.
We’ll maintain you posted as we be taught extra. If this information impacts you, I additionally advocate trying out Challenge Zero’s submit on the state of affairs by following the hyperlink beneath.
