What is the modem model in the Fairphone 4?

Google’s security research unit is sounding the alarm on a set of vulnerabilities it found in certain Samsung chips included in dozens of Android models, wearables and vehicles, fearing the flaws could be soon discovered and exploited.

Google’s Project Zero head Tim Willis said the in-house security researchers found and reported 18 zero-day vulnerabilities in Exynos modems produced by Samsung over the past few months, including four top-severity flaws that could compromise affected devices “silently and remotely” over the cellular network.

In late 2022 and early 2023, Project Zero reported eighteen 0-day vulnerabilities in Exynos Modems produced by Samsung Semiconductor.

“Four vulnerabilities allow an attacker to remotely compromise a phone at the baseband level with no user interaction, and require only that the attacker know the victim’s phone number.”

Anybody know the manufacturer of the modem in the FP4?

The safe bet would be to ask Fairphone.

Exynos is Samsung’s SoC brand, the FP4 uses a Qualcomm Snapdragon SM7225.

The built-in modem is called “Snapdragon X52 5G Modem”, the manufacturer is Qualcomm.
