We're having an outbreak of DRIVER_IRQL_NOT_LESS_OR_EQUAL BSOD's in driver NETIO.SYS. Netio.sys caused BSOD's are usually tied to network drivers but that doesn't make sense because this started happening all of a sudden on multiple computers. These are fully patched/updated Windows 10 Pro computers. The common thing we're seeing is Sophos was updated to version 2022.2.1.9 around 7/20/22 on all of them. Any insight from Sophos on if the blue screen of death crashes are being caused by the latest version of Sophos?
Yes, it's mindblowing that it would take a multi billion $ company this long to fix it. At least have an option for those affected by bad sofwtare updates to rollback to the previous version instead…
Hi all. Just a note but after examining memory dumps from our users who had the BSOD issues, we found that all users affected were using firefox. The dump file shows that firefox was the program that actually launches the blue screen in relation to some interaction with Sophos. Can anyone confirm if this sounds accurate for your instances as well? Or have you had users who were utilizing chrome and not any brand of firefox?
It has happened with Chrome and Edge for us. The culprit is Cisco AnyConnect and streaming data in the browser. In our case it’s phone traffic through RingCentral.
