Windows 10: Issue on a Lenovo Y700 running 22H2 with Security Update KB 5026361 and Fltmgr.sys driver

MerleOne_92 · May 21, 2023

Hi,I have a Lenovo Y700 running Win10 Home, 22H2, build 19045.2728. It was stable until beginning of May when update KB5026361 was installed. Immediately after reboot, I started to have several BSOD, all referring to a fault in fltmgr.sys driver. Since the issue appeared just after the update nothing else was changed, I uninstalled the update and stability returned. I also postponed all updates for several weeks but as soon as the update was pushed again, BSOD returned.Is this a known issue ? Is there a way to "ban" this update ? How to report efficiently this issue ?Thanks.PS : the dump rep

BSOD on a brand new Lenovo Y700 running Windows 10

Hey guys,

a week ago I bought a brand new Lenovo Y700 with a pre-installed SSD. Ever since I am experiencing BSOD while opening for example Photoshop or Lenovo Solution Center. 99,9% of the times it gives me this error: "kernel security check failure" and the other 0,01 it's something else, but still BSOD.

Here is my dump report.

Any suggestions will be appreciated!

a GREAT. and general problem with Lenovo Y700-17ISK

Hi Alex,

I highly appreciate your efforts.

Which troubleshooter did you run for bluescreen?

Is your Windows activated?

It could be due to missing/corrupt drivers or missing updates or hardware changes.

I suggest you to try the steps provided below and check if it helps.

Restart the computer a few times and check for Windows Updates.

In the Search box on the taskbar, enter Windows Update, select Windows Update. On the Windows Update page, select Check for updates.

Try to run the hardware and USB troubleshooter in the link below and check.

Error codes in Device Manager in Windows:

https://support.microsoft.com/en-us/kb/310123

Also, try to run the Power Troubleshooter.

Power troubleshooter will automatically fix some common issues with Power Plans. Run the Power troubleshooter to adjust your computer's power settings. The Power troubleshooter checks things like your computer's timeout settings,
which determine how long the computer waits before turning off the monitor display or entering sleep mode. Adjusting these settings can help you conserve power and extend your computer's battery life.

Press Windows Logo Key+X then click on Search option.

Type Troubleshooting.

Select Troubleshooting and click on
System and Security.

Click on Power and follow the onscreen steps.

For reference: (Developer Content) Bug Check 0x9F: DRIVER_POWER_STATE_FAILURE

Bug Check 0x9F DRIVER_POWER_STATE_FAILURE - Windows drivers

Dell Client Platform Security Update for Dell dbutil Driver

The vulnerability exists in the dbutil_2_3.sys driver. This driver file may have been installed on your Dell Windows operating system when you used firmware update utility packages, Dell Command Update, Dell Update, Alienware Update, Dell System Inventory Agent, or Dell Platform Tags, including when using any Dell notification solution to update drivers, BIOS, or firmware for your system. To best protect yourself, Dell recommends removing the dbutil_2_3.sys driver from your system by following one of three options listed in Remediation Step 1 below.

Dell has remediated the dbutil driver and has released firmware update utility packages for supported platforms running Windows 10, Dell Command Update, Dell Update, Alienware Update, Dell System Inventory Agent and Dell Platform Tags. For supported platforms on Windows when you:

install a remediated package containing the BIOS, Thunderbolt firmware, TPM firmware, or dock firmware; or

update Dell Command Update, Dell Update, or Alienware Update; or

install the latest version of Dell System Inventory Agent or Dell Platform Tags,

The remediated dbutil driver is installed on your system. Refer to Remediation Step 2 for details.[/TD]

Dell Technologies recommends all customers consider both the CVSS base score and any relevant temporal and environmental scores that may impact the potential severity associated with a particular security vulnerability.

Affected Products and Remediation

The vulnerable driver (dbutil_2_3.sys) was delivered to impacted systems in two ways: (1) via affected firmware update utility packages, and (2) via Dell Command Update, Dell Update, Alienware Update, Dell System Inventory Agent, or Dell Platform Tags, including when using any Dell notification solution to update drivers, BIOS, or firmware on your system. The tables in the “Additional Information” section below provide the following information:

Table A lists platforms with impacted firmware update utility packages, including BIOS update utilities, Thunderbolt firmware update utilities, TPM firmware update utilities and dock firmware update utilities.

Table B lists the end of service life platforms with impacted firmware update utility packages, including BIOS update utilities, Thunderbolt firmware update utilities and TPM firmware update utilities.

Note: The dbutil_2_3.sys driver vulnerability does not impact the actual firmware updates that these utilities deliver. Rather, the vulnerability exists in the dbutil_2_3.sys driver that is packaged with the firmware update utility.

Remediation Steps:
Impacted customers must complete 2 steps as follows:

Immediately remove the vulnerable dbutil_2_3.sys driver from the affected system using one of the following options from Step 1 below: download and run a utility to remove the driver from the system (Option 1), manually remove the driver from the system (Option 2), or on or after May 10, 2021, utilize one of the Dell notification solutions to run the utility (Option 3).

As described in Step 2 below, obtain and run the latest firmware update utility package(s), Dell Command Update, Dell Update, Alienware Update, Dell System Inventory Agent, or Dell Platform Tags as applicable.

Step 1: Immediately remove the vulnerable dbutil_2_3.sys driver from the affected system using one of the options below. NOTE: If you are using the Dell System Inventory Agent you must first download the latest available version (2.6.0.0 or greater) here.

Option 1 (Recommended): Download and run the Dell Security Advisory Update – DSA-2021-088 utility.

Option 2: Manually remove the vulnerable dbutil_2_3.sys driver:

Step A: Check the following locations for the dbutil_2_3.sys driver file

C:\Users\<username>\AppData\Local\Temp

C:\Windows\Temp

Step B: Select the dbutil_2_3.sys file and hold down the SHIFT key while pressing the DELETE key to permanently delete.

Option 3 (available by May 10, 2021): If you use one of the Dell notification solutions, you can use it to obtain and run the Dell Security Advisory Update – DSA-2021-088 utility.

Scenario 1: If your Dell notification solution is configured to automatically notify you of updates, and configured to automatically download and apply them, then this utility is automatically downloaded and applied for you.Scenario 2: If your Dell notification solution is not configured to automatically download and apply updates, obtain the utility via one of the Dell notification solutions , by clicking “Check for Updates”, and then selecting and applying Dell Security Advisory Update – DSA-2021-088.
Step 2: To prevent reintroduction of a vulnerable dbutil driver, obtain and run a remediated firmware update utility package, Dell Command Update, Dell Update, Alienware Update, Dell System Inventory Agent, or Dell Platform Tags as applicable.
For firmware update utility packages: With your next scheduled firmware update, download and apply the latest available firmware update utility which contains a remediated dbutil driver. Customers can use one of the Dell notification solutions to receive updated firmware update utility packages, as applicable.Notes:

For supported platforms running Windows 10, updates are available as of the publishing of this advisory. (See Table A)
