Multiple computers getting netio.sys BSOD after 2022.2.1.9 update

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?

  • We just started having an influx of users reporting BSODs with this same error this Monday and today so far.

    We have Dell computers. One user was experiencing it and after running all Dell Command Updates that seemed to resolve the issue for him.

    Others are reporting the issue even after all Dell Command Updates ran.

    Hi

    If possible can you configure an endpoint to do a complete memory dump while reproducing the issue and provide that along with an SDU log?  If you email - support@sophos.com  this will open a support ticket and if you PM me the case number I can send the instructions to you as well.
