Thanks for taking the time to report this bug and helping to make Ubuntu
better. There are some Distros that ship patches to the /dev/mem
handler, but these changes are not supported by the upstream kernel, and
Ubuntu has not had the resources to maintain a patch delta. Root users
have the capacity to examine per-process memory as well, so fixing
/dev/mem would still not change this. The primary reasons to stop
/dev/mem access is to avoid things like root-kit installation.
I'm unmarking this as private, as it is already a known public issue
with the Linux kernel's /dev/mem interface.
Please feel free to report any other bugs you may find.
