Frage an euch: Viele zögern, #GraphenOS zu installieren, obwohl es eigentlich recht einfach ist. Wie wäre es, wenn der Kuketz-Blog eine Dienstleistung anbietet, die die Installation gegen eine (social.tchncs.de)

@PC_Fluesterer @mynacol @BafDyce @katzenberger @nick Every ARM and x86_64 CPU is entirely closed source. CPU, GPU, MMU and everything else in them is closed source. This is not a negative or positive security property for this hardware but rather orthogonal to it. Even with reproducible builds, open source does not prevent a backdoor at all. That's clearly true based on the fact that unintentional, non-hidden critical vulnerabilities last for many years in open source projects. It's basic logic.

@PC_[email protected] @[email protected] @[email protected] @[email protected] @[email protected] CPU, GPU, MMU and all the other SoC components along with the RAM, SSD, cameras, Wi-Fi, Bluetooth, cellular, NFC, UWB and everything else in essentially any laptop, desktop, smartphone or tablet is closed source. What makes you think that your laptop has open source hardware and firmware? The highly inaccurate false marketing from companies like Purism? That's just false marketing misleading users into believing closed source hardware is open.

@PC_[email protected] @[email protected] @[email protected] @[email protected] @[email protected] Cellular basebands are very comparable to the basebands for Wi-Fi, Bluetooth, UWB, GNSS and other radios. They are not particularly special and do not have privileged access on a modern smartphone. Pixels have a well isolated cellular radio with a lot of extra hardening (https://security.googleblog.com/2024/10/pixel-proactive-security-cellular-modems.html). Compromising cellular radio with an exploit is very difficult and does not provide control over the device. You'd need an OS exploit from there.
