Does rancher's docker container run a process named exe in linux?

I found a process named “exe” running on the VM where my Rancher docker container was running. When I stopped the Rancher container, the exe process disappeared from the list of running processes. This exe process was eating >50% of my CPU on the VM.
Anybody ever see this before?

The VM is running a fully updated Ubuntu 22.04.4 LTS.

There are 381 instances of “exe” in /proc

. . . etc.

I could see this exe in /usr/bin/top but /usr/bin/ps could not find it.
