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've been having this BSOD randomly since april on about 100 laptops (dell latitude 5480/5580) and 90 ish desktops (dell optiplex 3080). The desktops were doing it hourly until we disabled the wifi card in the bios, as for the laptops, it has been a couple a day blue screening and we figured it was a wifi driver issue and have been looking for an update there. Is there an chance it was actually caused by some prep work for this update?
