Hello everyone,
We installed Forticlient on multiple machines and I have recently been getting BSODs on some of them. They all points to Fortiproxy sending bad arguments/parameters to NETIO.sys. The machine here is using Windows 11 22H2, and the Forticlient version at the time was 7.0.11.
Here's the stack from the minidump (happens in process Fortiproxy) :

I have already seen a similar forum post here: https://community.fortinet.com/t5/Support-Forum/Netio-sys-Blue-screen-of-Death-BSOD-Multiple-machine...
In the meantime, we have updated to 7.0.12, but we are not certain if this issue has been fixed.
If anybody knows anything, or if Fortinet might take up this issue, that would be great.
Thank you very much.

Looks like this is potentially a known issue being tracked under Bug ID 0984763. It is caused by an incompatibility with FortiClient and certain antivirus.
You can open a ticket with TAC who can provide you an interim FortiClient to resolve this issue.

Thank you for your answer Jonathan.
We are currently not using any third party antivirus, just Windows Defender. The problem also appears to be restraint to a couple of machines only. We have a whole lot of laptops, all configured the same way, and we're not getting reports for many BSODs, which would be the case if the problem was more widespread.
Is there anything else coming to your mind? Would you like me to send you the minidump file?
As an interim solution we have fully reset the affected PCs and updated them to W11 23H2. We also updated Forticlient to 7.0.12. We'll see if the problem comes back. I'll keep you posted.
Did you ever resolve? We are having the exact same issues. We are getting over 1k bluescreens a month at this rate across our ORG. Running Defender and Forti 7.2.4
Sadly not. We're still investigating. Some people say it's Intel drivers, but we can't definetly find it out as the problem keeps happening completely randomly.
I will update you as we progress. Would love any new info you may find as well.
Checking back. Anything new on your end? We are testing 7.0.10 per Forti. Microsoft is still pointing to Forti as well.
Still nothing new on our end sady. Bluescreens keep happening randomly and we couldn't use certain PCs long enough yet to make sure that the issue actually went away with the things we're trying...
