Google warns users to take action to protect against remotely exploitable flaws in popular Android phones

Google`s safety studies unit is sounding the alarm on a fixed of vulnerabilities it determined in sure Samsung chips protected in dozens of Android models, wearables and cars, fearing the failings may be quickly observed and exploited.

In a weblog post, Google`s Project Zero head Tim Willis stated the in-residence safety researchers determined and mentioned 18 zero-day vulnerabilities in Exynos modems produced through Samsung over the last few months, such as 4 top-severity flaws that would compromise affected gadgets “silently and remotely” over the mobile network.

“Tests performed through Project Zero affirm that the ones 4 vulnerabilities permit an attacker to remotely compromise a telecellsmartphone on the baseband stage and not using a person interaction, and require simplest that the attacker recognise the victim`s telecellsmartphone number,” Willis stated.

By gaining the capacity to remotely run code at a tool`s baseband stage — basically the Exynos modems that convert cellular alerts to virtual records — an attacker could be capable of advantage near-unfettered get right of entry to to the records flowing inside and out of an affected tool, such as mobile calls, textual content messages, and cellular records, with out alerting the victim.

As disclosures go, it`s uncommon to look Google — or any safety studies firm — sound the alarm on high-severity vulnerabilities earlier than they're patched. Google mentioned the chance to the public, declaring that professional attackers “could be capable of speedy create an operational exploit” with constrained studies and effort.

Project Zero researcher Maddie Stone wrote on Twitter that Samsung had ninety days to patch the bugs, however hasn`t yet.

Samsung showed in a March 2023 safety list that numerous Exynos modems are vulnerable, affecting numerous Android tool producers, however furnished little different details.

According to Project Zero, affected gadgets encompass almost a dozen Samsung models, Vivo gadgets, and Google`s very own Pixel 6 and Pixel 7 handsets. Affected gadgets additionally encompass wearables and cars that rely upon Exynos chips for connecting to the mobile network.

Google stated that patches will range relying at the manufacturer, however mentioned that its Pixel gadgets are already patched with its March safety updates.

Until affected producers push software program updates to their customers, Google stated customers who desire to guard themselves can transfer off Wi-Fi calling and Voice-over-LTE (VoLTE) of their tool settings, which will “eliminate the exploitation chance of those vulnerabilities.”

Google stated the ultimate 14 vulnerabilities have been much less extreme due to the fact they required both get right of entry to to a tool or have insider or privileged get right of entry to to a cellular carrier`s systems.
