I was wondering if the major root exploit that was found 2 months ago was fixed on the n900 kernel?

Since it's running 2.6.28 it might not be... Hopefully we can get 2.6.31 by december with all the updates?

If someone on the device can check the value of vm.mmap_min_addr that would help.

As I don't think pulseaudio is used on the device, nor SELinux/AppArmor, the only way to exploit this would be to be able to map something at address 0.

Yes, http://repository.maemo.org/pool/fre...08+0m5.diff.gz does contain the patch.

I think it's very unlikely that Fremantle will see anything other than 2.6.28. Backports of specific patches are a different thing of course.

Code:
Nokia-N900-41-10:~# cat /proc/sys/vm/mmap_min_addr 
4096
