Microsoft warns that Windows 10 update will break some Bluetooth devices

  1. First reported by WindowsLatest, Microsoft said its new security update (CVE-2019-2102) addresses a vulnerability by intentionally preventing connections between the OS and “unsecure” Bluetooth devices.

    “You may experience issues pairing, connecting or using certain Bluetooth devices after installing security updates released June 11, 2019,” the company writes.

    Microsoft notes that any device using well-known keys to encrypt connections may be affected, which includes certain security fobs. All versions of Windows 10 will receive the update, along with Windows 8.1. Exactly how many devices might be borked by the update is unclear, and it appears that the only way to find out is if your Bluetooth accessory stops pairing.

    Microsoft did say that advanced users can verify if their Bluetooth device is affected by checking the Event Log for the following event:

    The Redmond company offered a solution for those who find their Bluetooth devices aren’t working: “contact the manufacturer of your Bluetooth device to determine if a device update exists.” If no updates exist, you’re left with the choice of avoiding the update, rolling it back, or buying a replacement device.

    While we’ve seen plenty of Windows updates unintentionally break features in the past, this time it's an intentional change. Microsoft says it's there to make a computer more secure, but some users aren’t happy about the situation.

    For what reason? Closing a security hole large enough to drive a Mac truck through?

    See, if the OS isn't secure, people complain about it. But if the security holes are fixed and some non-conformant things break, people complain about it. There's literally no way to win.

    There is nothing wrong with the update. It's closing a security hole. Time to update your Bluetooth device. Don't like it, well maybe let the Bluetooth manufacturers know and ask them to offer a update/replacement since it wasn't the consumers fault.

    Good Lord. Another update, another problem.

    And people ask why I'm still using "Windows 7". SMH.

    If MS releases an update that renders some devices useless, it's up to *MS* to provide working drivers, not tell users, "Tough $#!+. Pray your device manufacturer released an update."

    Its a security risk they are responsible not for the any device that the user uses.

    I am sick of windows and when I initially upgraded from 8.1, I lost my Bluetooth and Blu-ray and was told it must have never existed by a Microsoft tech and no matter what fix I did, it didn't matter. I know it existed because I used both and aside from purchasing new hardware that I can't afford, I never got it fixed and every update for Win10 they release causes problems on EVERY device I have that is running it. I know Apple products are pricey but I don't ever hear about them making everyone's PC's problematic like Windows! I think it's wrong to release something that isn't user friendly for all devices running it. I mean minor glitches are expected as devices vary as well as the user but this is getting ridiculous and I feel that Windows 10 is the beginning of the end for Microsoft. I don't consider myself an expert with computers but I am no dummy either and continuing to use an OS that sucks makes me feel like one!! I have an Asus X551MA and it's like Windows forgot about Asus users when they created Windows 10 initially and now for every fix or update they send out, 5 more things go wrong!

    If it breaks something and they don't also provide the fix, it's a problem.

    If this is a serious issue, Windows 7 (which is still currently supported) should also be affected and a patch for it released. Where is it?

    And wouldn't the same device have the same security flaw when used from Linux? :bomb:

    Except that it's not a big problem. No one is going to hack a connection to a headset and even if they did, what they would gain is extremely minimal. Microsoft has their head up their bums where security priorities are concerned.

    There is a good reason for this, Apple have left far more expensive equipment in the lurch over the years for less reason, I had to get a new NAS because of Apple "reasons".

    I tend to agree with you and MS should be commended for its work on trying to make Windows more secure. On the other hand MS is forcing updates on its users and doing so without giving them are really notice. And then there are the continued problems with updates. Even this morning I was reading about the latest update breaking some other aspect of Windows.

    I can only begin to wonder how frustrating it is to be a Windows user. Well, that not entirely correct because my employer requires me to use a Windows computer. Don't get me started . . . !

    Will this be pushed to Server 2019 also?

    I run a Bluetooth > Serial dongle I put in servers, and I'd hate to lose that functionality - as I can gain console access anywhere in an equipment room...without being tethered.

    I honestly think this is just a lazy way of fixing the issue. I'm sure there was a way to patch the security risk without disabling these bluetooth devices. Thousands upon thousands of people are going to have their computer reboot and their stuff isn't going to work, which is just bad practice to me. Not everyone comes to tech sites like these so they can prepare themselves/figure out the issue they're having. I feel microsoft simply didn't want to work hard enough to fix the issue so they just went the easy route and simply shut it all down. Terrible practice.

    I may be wrong here is well so correct me if I am but im not researching it. This issue could also effect mice and keyboards and this could literally prevent people from completing their work. I don't understand microsoft anymore. Once easyanticheat games are running well on linux without a passthrough or something I'm gone.

    This is the scenario where this patch could actually increase security... :)

    Edit: Except that no hacker would use win10 in the first place...

    I point out drivers that are conform to best practices shouldn't have any problems. And I can say for certain for a change like this most BT manufactures would have been informed. I'd be shocked if more then a couple dozen devices break, and most will get updates within a day or two.

    this is honestly microsofts fault for having a garbage operating system in the first place. the user shouldn't have to worried about stupid issues like this. one day they're going to release a windows update that accidently breaks the signal being sent to their monitor at the rate they're going. ever since gates stepped down the company has went completely south.

    No, it's up to the manufacturer of the device to release an updated driver that complies with security standards. Because a manufacturer is lazy and releases security flawed drivers does not put the onus on Microsoft to fix their ****. Microsoft is doing the right thing here.

    Microsoft is doing the right thing here by closing the gaping security holes. Kudos. Manufacturers, get your **** together and stop putting out devices with flawed drivers. The standards are out there. Use them.

    They aren''t shutting it all down. They are not allowing unsecure devices to connect via bluetooth after the update which is smart.

    ~sigh~ hours of wasted troubleshooting only to find out microsoft isn’t up front about not pairing bluetooth devices. I wonder which lame brain executive made that decision.

    You know, I wonder if anyone here actually bothered to read the security bulletin:


    This is a case where a potential vulnerability exists within the BT spec itself, and MSFT is addressing it via an OS update. This isn't strictly an OS problem, but a problem that can arise from the way device drivers implement Long Term Key's.
