Google has disclosed several security flaws for phones that have Mali GPUs, such as those with Exynos chipsets. The company's Project Zero team says it flagged the problems to ARM (which produces the GPUs) back in the summer. ARM resolved the issues on its end in July and August. However, smartphone manufacturers including Samsung, Xiaomi, Oppo and Google itself hadn't deployed patches to fix the vulnerabilities as of earlier this week, Project Zero said.Researchers identified five new issues in June and July and promptly flagged them to ARM. "One of these issues led to kernel memory corruption, one led to physical memory addresses being disclosed to userspace and the remaining three led to a physical page use-after-free condition," Project Zero's Ian Beer wrote in a blog post. "These would enable an attacker to continue to read and write physical pages after they had been returned to the system."Beer noted that it would be possible for a hacker to gain full access to a system as they'd be able to bypass the permissions model on Android and gain "broad access" to a user's data. The attacker could do so by forcing the kernel to reuse the afore-mentioned physical pages as page tables.Project Zero found that, three months after ARM fixed these issues, all of the team's test devices were still vulnerable to the flaws. As of Tuesday, the issues were not mentioned "in any downstream security bulletins" from Android manufacturers.Engadget has contacted Google, Samsung, Oppo and Xiaomi to ask when they will deploy the fixes to their Android devices and why it has taken so long for them to do so. As SamMobile notes, Samsung's Galaxy S22 series devices and the company's Snapdragon-powered handsets aren't affected by these vulnerabilities.

Critter & Guitari's lineup of hackable music computers and video synths are undeniably unique. They do things that practically no other instrument can, plus they're probably the most visually distinctive portable music devices out there. Its latest creation is the 201 Music Synthesizer, an arguably long overdue replacement for the company's first product the Pocket Piano. Like its flagship Organelle, the 201 is built on open source software, specifically Pure Data and Faust. But rather than trying to be all things to everyone, it's more narrowly focused. It ships with six built-in synth engines covering chiptune-style bleeps, analog-esque sounds, drum samples, physical modeling (likely via Karplus Strong), and vocal synthesis. Rather than four knobs that vary in purpose depending on what patch you've loaded (which may or may not have particularly good documentation, depending on who created it), the 201 has three parameter knobs for envelope, tone and "surprise" for when you just want a happy accident. One of the things that makes the 201 really standout though, is the pattern generator and sequencer. While you can simply play notes live and record them for later recall, the synth can also create patterns for you. A couple of presses on the unique maple keys and the 201 will start spitting out simple octave jumps, arpeggios or random polyphonic chaos. And if something strikes your fancy, you can save that as well. And you can save literally thousands of sequences to the included 8GB microSD card. Like the Organelle, you can actually hack together your own patches for the 201 using Pure Data or Faust, but that's more of a nice bonus than the main selling point here. Under the hood of the 201 is a 900Mhz ARM processor with 512MB RAM, which should be plenty for most synth patches, but it's not quite as powerful as the Organelle M. The 201 also has a built-in speaker, a 1/4-inch stereo out jack, 1/8-inch MIDI in and out, USB-A for connecting MIDI controllers, and USB-C for accessing the files on the microSD card.Of course, to be a true replacement for the Pocket Piano, the 201 also needs to be portable. So, in addition to the AC adapter, it can be powered by three AA batteries. And at about one pound and a little over nine-inches long, it's pretty easy to toss in a backpack. The Critter & Guitari 201 Music Synthesizer is currently crowd funding over at Kickstarter and has already surpassed its goal. If you'd like to secure one when they start shipping in April of 2023 you can back it before December 20th for $295.

Black Friday may still be a few hours away, but we're already seeing a bunch of great deals on our favorite tech. This comes after a slow trickle of deals popping up across the web ever since the start of November. While we don't have the supply chain issues we did last year, it's still a good idea to start your holiday shopping as early as possible even if it's just a few hours before the biggest sale day of the year. The sooner you check off items from your list, the sooner they'll arrive and you'll be ready to go for the holidays. To make things easier for you, we've collected the best early Black Friday tech deals here so you don't have to go searching for them.Bose QuietComfort 45Billy Steele/EngadgetThe Bose QuietComfort 45 headphones are back on sale for $249 right now, or 32 percent off their usual price.

However, US users are capped at 65W SUPERVOOC, but that's still the speediest charging standard available stateside. Otherwise, we also appreciated the 10 Pro's lovely 120Hz display and its fast face-unlock feature.Buy OnePlus 10 Pro at Amazon - $549iRobot Roomba j7Valentina Palladino / EngadgetiRobot's Roomba j7 is on sale for $349 right now, which is the cheapest we've seen it, and you can get the j7+ for $599.

And if you want it to wake you up visually, too, its sunrise alarm will slowly adjust the screen's brightness to wake you up more naturally.Buy Echo Show 5 at Amazon - $35Amazon Echo DotAmazonThe latest Echo Dot has dropped to $25, and that's the first real discount we've seen since the device came out a few months ago. Amazon added a bigger speaker inside this Echo Dot for improved sound, and it has a new built-in temperature sensor as well. That will come in handy if you have other smart home devices you control with Alexa because, if the temperature sensor reaches a certain level, you can program a routine to, say, start a fan to keep your environment precisely how you like it. The new Dot can also pair with an Eero WiFi system to add up to 1,000 extra square feet of coverage.Buy Echo Dot at Amazon - $25Kindle PaperwhiteAmazonAmazon's Kindle Paperwhite has been discounted to $95 for Black Friday.
