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?

  • Sophos, we really need a final fix for this! Any official announcements on Update release date? If yes, please update KB accordingly! We‘re talking about nearly three month without official fix available (except beta patch on manual request).

    or do general rollback to 2022.2.1.9?

    Degrading security by disabling webcontrol and real-time scanning is no real acceptable workaround for multiple weeks/month! Aren‘t we talking about security?!

  • Honestly, this whole episode has really diminished my estimation of Sophos as a vendor. Not the fact that they had this issue, the fact that it took 3 months to get close to a fix, or the number of hoops that we have needed to jump through to get a temporary patch. Just a waste of our time. 

  • Exactly. Not only did it take forever for a beta patch, made it hard to get is just not good. Then the file could get replaced when sophos updates.... The big question is why Sophos chose not to revert back to previous code that was 100% working instead of 3+ months of this.
