Windows 10 update is breaking some webcams – but a fix is on the way

Image Description

Windows 10’s cumulative update in February for May 2020 Update (and October 2020 Update) systems reportedly has a bug with the potential to disable some webcams, and Microsoft is now working on a fix for this problem.

The issue with the KB4601319 update was flagged to Microsoft via its Windows 10 Feedback Hub, as spotted by Windows Latest, and it appears to affect Intel RealSense Depth and Razer Stargazer cameras.

A Microsoft software engineer stated: “Thank you for bringing the issues with Intel RealSense Camera to our attention. We are aware of the issue and are working on a fix. In the meantime, if you need to get your camera working, please follow the instructions on how to remove an installed Windows Update.”

In other words, for the time being, if your webcam has been rendered useless by the KB4601319 patch, your only recourse is to remove the update (if you’re not sure how, we’ve got a handy guide on that).

Peripheral fail?

According to Microsoft’s release notes, cumulative update KB4601319 provides security improvements for using peripherals like a mouse, keyboard, or stylus, as well as updates for verifying passwords.

There is a known issue with Discord (although that’s resolved in the latest update for the Discord app), and some other reported problems as seen on Reddit, with the patch actually breaking the mouse and keyboard for one user. This isn’t the only report of issues with a mouse after applying KB4601319, either, as Windows Latest notes.

Worryingly, there are scattered reports of nasty Blue Screen of Death (or black screen) crashes with the update, as well, but fortunately these don’t seem to be widespread.

  • This dangerous Windows zero-day lets you instantly become an admin

    Cybersecurity researchers have publicly disclosed an exploit for a new Windows zero-day local privilege elevation vulnerability that gives admin privileges in Windows 10, Windows 11, and Windows Server releases.

    Exploiting this bug, threat actors with access to a limited Standard user account on a vulnerable Windows installation can elevate to SYSTEM user privileges, and then move laterally within the network.

    Abdelhamid Naceri working with Trend Micro’s Zero Day Initiative had originally discovered the vulnerability, which Microsoft had fixed as part of the November 2021 Patch Tuesday. However, examination of Microsoft’s patch led Naceri to discover a bypass that led to the more powerful new privilege elevation vulnerability.

    Powerful PoC

    Naceri has published a working proof-of-concept (PoC) exploit for the new zero-day, saying that it works on all supported versions of Windows.

    “This variant was discovered during the analysis of CVE-2021-41379 patch. the bug was not fixed correctly, however, instead of dropping the bypass. I have chosen to actually drop this variant as it is more powerful than the original one,” wrote Naceri.

    Naceri claims that his PoC is “extremely reliable,” and he’s tested it in multiple conditions and Windows variants and found that it works in every attempt. Furthermore, he explains that the PoC even works in Windows server installation as well, which by default doesn't allow standard users to perform MSI installer operations.

    “The best workaround available at the time of writing this is to wait [for] Microsoft to release a security patch, due to the complexity of this vulnerability. Any attempt to patch the binary directly will break [the] windows installer,” suggests Naceri.
