Last week, Microsoft rolled out significant updates with dozens of different patches for its Windows 11 and Windows 10 operating systems. Among them was a fix designed to address a vulnerability found in the Windows kernel and related to access to confidential information. As it turned out, installing the patch that eliminates this vulnerability can lead to new problems.

The patch in question is intended to fix a vulnerability labeled CVE-2023-32019. Its description states that “an authenticated user (attacker) can gain access to information on the PC, through a vulnerability in the Windows kernel. The attacker does not need to have administrator rights or other elevated user privileges. Once access is gained, the attacker can view the contents of dynamic memory, through a privileged process initiated by an authorized user of the system.”

To address this vulnerability, Microsoft released patches KB5027215 (for Windows 10 versions 21H2 and 22H2, as well as Windows Server 20H2) and KB5027231 for Windows 11. As it turned out, their installation can break something in the operating systems. For instance, after installing update KB5027231, some Windows 11 users complained that their antivirus program, Malwarebytes, started blocking the launch of the Chrome browser on their PCs. Meanwhile, other users report a very long installation of the KB5027215 update on Windows 10 — for some, it took up to half an hour.

As of now, Microsoft has acknowledged the problem of the aforementioned updates and has defaulted to disabling them. If desired, the user can enable them through the system registry. The company provided instructions on how to do this on its official website. With the future release of security updates, the operation of these patches will be enabled by default.
