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 are experiencing the same issue as well on multiple Lenovo models (T14, T480, T490) over the past few days. We are running core agent 2022.2.1.9 as well as Cisco AnyConnect 4.10.05111. I'm not sure about the relation to AnyConnect though; BSODs are happening regardless of VPN connection status.

    We are currently using the workaround posted by (disabling "Realtime-Scanning - Internet" and "Web Control"), which seems to help but would rather be avoided of course.
