Windows 10: BIOS Update over Windows Updates causes Dell Laptop to freeze up on Dell logo

J-C R · Feb 23, 2023

Hi Forum,it took my attention that three of the Dell Clients in the company experienced the same behaviour after a BIOS Update came through the Windows Update Tool. Before the BIOS was updated a couple of Intel updates were installed therefore I express my concern here. The shown behaviour is that after the installation, the equipments most be reboot and by booting up they remain on "loading" at the initial Dell Logo, after that windows can't be booted anymore but only on safe mode. After a Systemrepair performed in the safe mode I was able to boot up windows again not alway

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

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.

Alienware (Dell) BIOS update

Denis @Try3

I have started a thread here to try to better explain and not clog up Site Bugs.

Site Bugs and Suggestions [4]

Normally, since I've had this machine, about 3 1/2 years, BIOS updates are shown to me as part of the Alienware Update app or if I go to Dell Support and put in my Support number. I then download the .exe shown for the update, just like any other Dell update. When I run the executable, it does a restart and as you say goes thru a very verbose update process, all steps being display in the BIOS update screen. Then normal restart and all comes up normal.

That is the normal way I have been doing it for years. This time, when I did a check for updates, the WHQL BIOS (firmware) had already been installed by WU (not me) and was waiting for a restart. I had few choices. I did the restart. It started the BIOS update process but the verbose messaging was not there, just the message "Updating system files" or something like that. It did the update, did a restart and all came up normally.

What I am trying to explain is this update thru WU from BIOS version 1.0.22 to version 1.0.23 went thru perfectly from all I can see: (Your batch file)

From BIOS:

System Information:

From Device Manager:

This is normal for me, it takes a while to get the info updated here. Couple of weeks it will say 1.0.23.

What's real is your .bat, the BIOS pic, and System Info.

Now to the question. I saw all the links you provided. I've been to all of them before. When I go to Dell Support, enter my Service Tag Number, scroll down the Drivers section, I get this as the most current.

Obviously not so. And I cannot find any reference anywhere on the 'net to version 1.0.23.

That is why I asked @firebird if he had any other info since it appeared he had access to info I do not:

Dell Inspiron laptop Windows 10 stuck on Dell logo screen!!!!

I have a Dell Inspiron laptop Windows 10 and it won't advance past the Dell logo screen. The computer turns on, the Dell logo appears for a few seconds, then the screen goes black, and then it does it all over again......the Dell logo appears, and screen
turns black...and on and on.......

I checked a few other forums and removed the battery, removed the power cable, held the power button down, powered it back on, it didn't work. I did a system diagnostic check and it came back good, with no problems.

Help!! Any suggestions?

Thanks in advance,

Todd
