Every single command I run gives me permission denied as root, this happened shortly after I changed /etc/fstab and remounted ext4.

The only commands I appear to be able to run is echo and cd, not that it is much help, all others I have tried show the following:

bash: /bin/ls: Permission denied

bash: /bin/bash: Permission denied

bash: /bin/mount: Permission denied

bash: /bin/chmod: Permission denied

All running programs are continuing to run, I also cannot SSH in as that also gives me permission denied so only my existing connection is working. I believe it may be caused by noexec but I am unable to run mount to fix it and it was on the root file system. Also I would rather not restart if at all possible and since it was changed in fstab it would likely happen again.

I have exhausted all my ideas and searching neither mount or chmod have helped as they are permission denied as almost every other command I have thought of.
