You might be using a hacked Dell laptop right now, and wiping Windows won't save you
Dell Latitude 5450. | Image by Dell Security in the digital age is no joke and when a major breach hits, things get serious fast. Now, a wide range of newishly discovered vulnerabilities is putting millions of Dell laptops at risk – and if you are using one, especially in business or government settings, it's time to act fast. A new report reveals that more than 100 Dell laptop models, mainly from the Latitude and Precision lines used by enterprises, cybersecurity experts and government agencies, are affected by a set of critical firmware vulnerabilities. These flaws could give attackers persistent access – even if you wipe and reinstall Windows. The flaws, collectively named "ReVault", affect the Broadcom BCM5820X security chip embedded in Dell's ControlVault3 firmware. This chip is designed to protect passwords, biometric data and encryption keys – but in this case, it could do the opposite, letting attackers steal that info and stay hidden inside your system. This is how a device could be compromised. Dell has confirmed the vulnerabilities and rolled out security updates, but if you are in charge of managing a fleet of Dell machines, now is the time to make sure those updates are actually getting installed. What's ControlVault3 and why does it matter? Dell's ControlVault is a hardware-based security system – a kind of digital vault – that stores your most sensitive info, like passwords, fingerprints and security codes, outside of your regular OS. It lives on a separate board inside the laptop called the Unified Security Hub (USH) and connects to smart card readers, NFC and fingerprint scanners. Cisco Talos researchers found five major flaws in ControlVault3 and ControlVault3+ firmware: CVE-2025-24311 – Out-of-bounds read → info leak CVE-2025-25050 – Out-of-bounds write → code execution CVE-2025-25215 – Arbitrary memory free → memory corruption CVE-2025-24922 – Stack-based buffer overflow → code execution CVE-2025-24919 – Unsafe deserialization in Windows APIs Each of these scored above 8.0 on the CVSS scale, making them high-severity. Combined, they can be used in extremely dangerous ways – including full system compromise. The worst part? These flaws can survive a full Windows reinstall. Because the vulnerabilities sit below the OS in the firmware layer, they can give attackers persistent access – and antivirus software won't catch it. The research team showed how even non-admin users can trigger these flaws through Windows APIs, potentially stealing cryptographic keys and modifying the firmware itself. And even without remote access, an attacker with just a few minutes of physical access could open the laptop and connect directly to the USH board via USB, bypassing system login and even full-disk encryption. And yeah, it gets wild – the researchers showed how they could trick a compromised ControlVault chip to accept any fingerprint, including objects like vegetables, as valid biometric input. What should users and admins do? First, update now. Dell has been releasing firmware patches and drivers since March 2025 and in many cases, they are being pushed through Windows Update. The researchers also recommend: Disabling ControlVault services/devices if you are not using fingerprint, smart card, or NFC readers. Turning off biometric login when leaving your laptop unattended. Using Enhanced Sign-In Security (ESS) in Windows for extra protection against physical tampering. Enabling chassis intrusion detection in BIOS, if available. Also, endpoint detection tools could help flag suspicious firmware access attempts, and unexplained crashes in Windows Biometric or Credential Vault services could be signs something's wrong. Why this matters more than ever Firmware components like ControlVault are full computing systems on their own – they've got memory, processors and software. And that means attackers exploiting them can sidestep traditional OS-level protections completely. – Cisco Talos researchers, August, 2025 Bottom line: firmware vulnerabilities like ReVault are dangerous, sneaky, and easy to overlook. If you are running a Dell business laptop, this isn't one to ignore.

No more peeking: Samsung closes the door on early One UI leaks
We all know that the world of mobile tech is full to the brim with leakers, who get their hands on whatever companies try to hide about upcoming products or releases. And as much as we love these leakers (the hype about new stuff is real), companies don't particularly like them. Over the past few months, a lot of One UI 8 firmware builds (internal ones) have been leaked for multiple models of Galaxy phones. This gave us a very detailed early look at what Samsung was planning in terms of software. Well, it seems this won't happen again, at least not this way. A few months ago, a curious dev found a way to locate and download under-development One UI firmware files. These files were meant for Samsung's internal testing. And this is what brought us early looks over One UI 8 for the Galaxy S25 Ultra, Z Flip 6, and Fold 6. Now, the folks at SamMobile confirm that, unfortunately, for all the curious folks who want to see early builds, Samsung has fixed that loophole that allowed people to access its internal test server. That server was used to send software updates for Galaxy phones, tablets, and smartwatches, but for internal testing. Now, unless someone else manages to find another loophole, these internal One UI firmware files can't be accessed. So yep, this pretty much means not to have any hopes of seeing early builds of One UI 8 .5, which may come with the Galaxy S26 series. Also, we won't be able to know, at least not in this way, new software features under development for Samsung's devices. Of course, you can still download publicly released firmware files; this has nothing to do with the usual downloads for firmware (the official ones). And also, beta builds will continue to exist to give people an early look (officially) at new builds of One UI. So we're likely going to see One UI 8 .5 before it releases with the Galaxy S26 , because it will likely first be beta tested on the Galaxy S25 phones.

Confirmed: Nintendo's Switch 2 can work with existing docks and webcams after replacing their firmware
Over the last two weeks, I've sought to uncover why the Nintendo Switch 2 didn't work with a host of USB-C accessories that worked perfectly fine with other devices, including third-party docks and some of the best-reviewed webcams. But today, I have first-hand confirmation that existing gadgets can work — as long as their manufacturers issue the right firmware updates, and as long as Nintendo doesn't break compatibility from here on out. You shouldn't necessarily need to buy a brand-new gadget to plug a TV or video glasses into your Nintendo Switch 2. Three manufacturers have already proven that firmware updates are enough for now, and hopefully more will follow! The existing gadgets I just successfully tested are: the AverMedia Elite Go GC313 Pro and AverMedia Core Go GC313 compact charger docks, the Elgato Facecam MK.2 webcam, and the Viture Pro Mobile Dock for the company's AR glasses. None of them worked with the Nintendo Switch 2 at launch, but each now has firmware updates available, and I was able to get them all working in my own home — and bust a few additional myths about Switch 2 compatibility. The gadget: Elgato Facecam MK2 The story: Elgato was one of the very first companies to promise it would update some non-working webcams to work with the Switch 2, and provided its own theories to The Verge on why they didn't work on day one. The company won't formally release its firmware updates for the Facecam MK2 and Facecam Neo till the end of July, but it sent us an early copy so I could show you video proof! Here, follow along with me as I install and test it for the very first time: (Sorry, I'm not allowed to share the early firmware update files.) What we learned: Elgato originally claimed the primary reason its cameras didn't work was that the Nintendo Switch 2 requires cameras to advertise a low-resolution 480p video mode, even if that's not the mode the Switch 2 winds up using. Sure enough: the USBView tool shows me that the Facecam MK2 now makes 480p the default video streaming mode that a USB host device (like the Switch 2) will see before anything else. Also: Remember when Ugreen told us that cameras wouldn't work with Switch 2 if they used the HID (human interface device) protocol? Weirdly, it seems Elgato actually added some HID references in its latest firmware. Here's the diff if you want to peek. The gadgets: AverMedia Elite Go GC313 Pro and AverMedia Core Go GC313 The story: I'd never even heard of these 100W GaN compact charging docks, the $130 GC313 Pro and the $90 GC313 — but it now appears they're the first and only portable docks for the Switch 2! (The Pro also doubles as a 1080p60 USB capture card, if you're wondering about the price delta.) The company has a whole page dedicated to Switch 2 compatibility firmware updates, mostly for its video capture devices, but also these portable docks, as well as a more traditional standing dock if you don't mind plugging your Switch in upside-down. What we learned: The firmware update was quick to install and the HDMI connection totally works — probably because AverMedia's dock is now using the exact same proprietary commands that we see Nintendo's official dock using. (Once again, I pulled out a USB-C PD analyzer to check. Before the update, AverMedia's dock didn't speak Nintendo's language and was quickly rejected; after the update, it did.) AverMedia's dock didn't work quite as reliably as the official dock in my early tests. It doesn't always connect the first time I plug it in, and there's also a short delay. Also note: the GC313 only seems to support vanilla 4K60 output with no HDR or VRR. As you'll read below, video glasses maker Viture has a firmware update that makes its gadgets compatible with Switch 2 — but takes away compatibility with the original Nintendo Switch. But I tested the AverMedia dock working with both generations of Switch, and Viture says it'll do the same in future. The gadget: Viture Pro Mobile Dock The story: This $130 dock is a battery pack that can power your handheld or phone, while routing its video to Viture's USB-C video glasses or a USB-C monitor. (The HDMI port is for input, not output to a TV.) With a firmware update, it gains support for Switch 2, but breaks support for the original Switch unless you downgrade afterwards. A future update will support both, though, Viture spokesperson Emily Wang tells The Verge. What we learned: Viture shipped me its dock pre-updated, so I didn't test before-and-after. But with the update, it totally works — after a bit of a delay, which seems to stem from some miscommunication between Viture's gadgets and the Switch 2, if I'm reading the USB-C PD traffic right. But after that miscommunication, I can see the Viture dock sends the exact same proprietary commands as Nintendo's official dock. One of the things we'd heard early on is that Switch 2 docking stations need to offer 20 volts of power for the Switch 2 to kick into TV mode — even though the handheld only actually uses 15 volts. But the Viture dock only advertises a maximum of 15 volts at 1.34 amps (20 watts in total), and yet Viture got video output working anyhow. We know these third-party docks are working with the Switch 2 as of today, and we expect more are on the way. (One I didn't get to test is this Hagabis, which fits the entire HDMI adapter into a cable instead of a dock — beware that the firmware update only official works with the 8K version which is black, not white or red and blue and keeps going out of stock.) But we don't know if Nintendo will move to block these accessories with firmware updates of its own. Today, it appears that each of these docks can fool the Switch 2 into thinking they're the official dock by emulating its commands, but several manufacturers admit that could lead to a game of cat-and-mouse where they have to issue new firmware updates to keep up with Nintendo. 'Similar to what Antank shared with you, it's true that we may need to provide firmware updates if Nintendo changes its protocol specifications,' Viture tells The Verge.
