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?

  • Yeah we are still having this issue. Just happened to our CEO in the middle of a meeting. My IT manager is suggesting that if they don't get this fixed soon that we will be researching a new AV solution for next year.

    It seems like the workaround has helped, but it's hard to verify at this point since it seems like not all of our users are actually reporting their BSODs.
