This is an exploitation vector that enables a virtual machine of a malicious actor to flip a bit in a memory page of a targeted virtual machine that’s active and operating on the same host as the hacker’s VM. FFS utilizes the hardware vulnerability for flipping of bits and a “physical memory massaging” primitive to redirect a victim page on an at-risk physical memory base. This is another variant of the Spectre hardware vulnerability. BCBS enables hackers to compromise the branch prediction capability of modern-day CPUs. After this, they can utilize the CPU’s cache as a side-channel exploit to extract data from the memory of other processes.

In addition to new ways of developing apps, there are always bugs that are found after software is released. The only way for application developers to fix these bugs is to issue new versions of their software. Updating your router only takes a few minutes of your time and it’s well worth it. Hit Browse and select the OpenWrt file you just downloaded. It was fixed after the tech made multiple phone calls to Spectrum over 2 hours. My router didn’t have a problem but Spectrum did something from their end to fix this problem.

If you have come across the Xfinity router blinking blue, then it means that your internet connection is in trouble. However, finding a reason behind the blinking blue light on the Xfinity router may not be straightforward. You’ll have to spend some time figuring out the exact issue. Home routers are particularly vulnerable because they’re exposed directly to the Internet.

Is operating system a firmware?

As soon as this Blu-ray player was installed, it prompted the user for a firmware update, which took place over a Wi-Fi connection and TV set. Cars and trucks are loaded with CPUs and microcontrollers that execute instructions stored in firmware. In the 21st century, along with oil changes and routine maintenance, auto mechanics often download and update firmware. As we touched on above, the purpose of any firmware update is to make a change to the existing software in some way. But what, exactly, any specific firmware update accomplishes depends on the context and the specific firmware version.

  • Only the temporarily stored files and the browsing activity will be deleted when the user exits the Guest mode.
  • On the Xfinity X1, you can reset the device in the Settings menu.
  • Desktop computers and laptops are not the only machines that require system software to be operated.

If you’re using a Mac, an additional layer of security can be achieved by using Filevault, which ensures that only logged-in users can access your drive’s data. With the firmware password set, no one will be able to access your Mac’s data by using an external hard drive. If you want to turn off a firmware password on your Mac that you’ve set up, the process is basically the same as above, except at step 4 you click Turn Off Firmware Password.

I basically removed the two memory chips and then only returned one of them into the other one’s memory slot. This mean’t that I took out half of the memory of the computer. This was obviously enough of a change to the hardware configuration for the computer not to lock up. Consequently I could boot up and get the computer working. My plan is to swap another stick of ram to replace the one I had to take out.

On the Router Settings page, you will be required to type in your username and password for the router. This article will guide you to update the firmware of your router using the NETGEAR genie software. Follow the manufacturer’s instructions for installing the firmware. Look closely for the link to the installation instructions, sometimes it can hide in plain sight. You can have all your network info at your fingertips. Manage your network usingSmart Home Manager from your computer.

Discovered a side-channel vulnerability that manipulates a unique part of the speculative execution process known as the return stack buffer . RSB can be manipulated via user code and direct pollution, where an adversary can insert a call instruction as a value pushed to the software stack and the RSB. Specifically, the stack is manipulated to ensure the return address doesn’t match the return buffer stack, allowing the bad actor to spoof data running on a CPU. The vulnerability may impact CPUs made by ARM, AMD and Intel.
