Google’s Venture Zero, a crew devoted to safety analysis, has uncovered main safety vulnerabilities in Samsung modems that energy gadgets just like the Pixel 6, Pixel 7, and a few fashions of the Galaxy S22 and A53. In response to the crew’s weblog publish, sure Exynos modems have a number of vulnerabilities that would result in a distant compromise of the telephone on the baseband stage with none person interplay. Which means that attackers may achieve management of the telephone with simply the sufferer’s telephone quantity.
Main Gadgets Akin to Samsung Galaxy S22, A53, Google Pixel 6 and Pixel 7 are Susceptible to Hacking with Only a Cellular Telephone Quantity
Moreover, the crew warns that skilled hackers may exploit this concern with minimal further analysis and growth. Regardless of the severity of the state of affairs, it looks like Samsung has been gradual to handle the issue.
Google has mentioned that the March safety replace for Pixels ought to patch the issue. Nonetheless, it’s not but obtainable for the Pixel 6, 6 Professional, and 6a. The researchers consider that the next gadgets could also be in danger: we’re speaking about cellular gadgets from Samsung. Together with these within the Galaxy S22, M33, M13, M12, A71, A53, A33, A21, A13, A12, and A04 sequence. Along with cellular gadgets from Vivo, together with these within the S16, S15, S6, X70, X60, and X30 sequence. Additionally, any wearables that use the Exynos W920 chipset and any autos that use the Exynos Auto T5123 chipset.
It’s necessary to notice that for gadgets to be weak, they need to use one of many affected Samsung modems. It is a aid for a lot of S22 homeowners because the telephones bought outdoors of Europe and a few African nations have a Qualcomm processor and use a Qualcomm modem, which is secure from these particular points. Nonetheless, telephones with Exynos processors, similar to the favored midrange A53, and European S22, may very well be weak.

The remainder of the vulnerabilities require both a malicious cellular community operator or an attacker with native entry to the system. Whereas that is nonetheless a priority, it’s not as extreme as the opposite vulnerabilities.
Venture Zero notes in its report that “With restricted further analysis and growth, we consider that expert attackers would have the ability to rapidly create an operational exploit to compromise affected gadgets silently and remotely,”.
Record of affected gadgets:
- Samsung Galaxy S22, M33, M13, M12, A71, A53, A33, A21, A13, A12 and A04 sequence.
- Vivo S16, S15, S6, X70, X60 and X30 sequence.
