Dell has simply launched a retroactive, high-priority software program patch for a whole lot of its machines, a few of which have preliminary releases relationship again to 2009.
The patch addresses an “inadequate entry management vulnerability” current within the dbutil_2_3.sys driver, which may be discovered on Home windows-equipped Dell techniques with user-installed firmware replace packages. Not all Dell machines are affected, however many are; 380, to be exact.
Impacted machines vary from Dell’s Latitude line-up to its Inspirons and even its G-series gaming notebooks. The vulnerability would enable somebody with entry to the machine (which might be obtained by means of malware) to escalate privileges and acquire kernel-level permissions.
Yow will discover a full list of affected machines on Dell’s web site — it is too expansive for us to listing right here. If considered one of your machines is on that listing, your first precedence ought to be to take away the offending driver out of your system.
There are three main methods to do that. First, you may obtain and run the DSA-2021-088 utility, which is able to automate the method for you — we would advocate this for most individuals.

Whether it is, choose the file, maintain down Shift, after which press the Delete key in your keyboard.
The ultimate technique includes utilizing considered one of Dell’s notification solutions (corresponding to Dell Command, Dell Replace, or Dell SupportAssist) to routinely apply the patch. That is probably the most handy choice (and the one which requires the least technical data), however Dell’s notification options will not help the DSA-2021-088 utility till Might 10, 2021.
As soon as you’ve got eliminated the susceptible driver, replace your system’s firmware at your earliest comfort to get a “remediated” model of the file. Dell’s notification options will work for this as properly.
And that is nearly it! Should you’ve eliminated the motive force and subsequently up to date your system, you have to be good to go. Hopefully, most individuals patch their machines earlier than an excessive amount of harm may be completed.
