Also side-channel attacks.

E.g. if one user downloads a container, and then for another user it is already in the cache, this gives the other user information about the first user.

Isn't this pointless, since if the other user has access to docker, they basically have root access to the machine?

[amelius]

I don't think users need to have root access to use Docker.

[Fire-Dragon-DoL]

No, but unless they run in rootless mode, they can mount any directory and write on it as root

They don't, but if you have given them access to Docker then it's just as if you had given them access to root.
