Bug Description
The mode of the latest kernel has changed so it is no longer readable
by non-root users:
-rw-r--r-- 1 root root 4336016 2010-10-17 01:37 /boot/vmlinuz-
-rw-r--r-- 1 root root 4336912 2010-11-24 12:46 /boot/vmlinuz-
-rw-r--r-- 1 root root 4523072 2011-03-08 18:47 /boot/vmlinuz-
-rw------- 1 root root 4523936 2011-04-11 05:24 /boot/vmlinuz-
This prevents people from using this kernel to boot qemu
virtual machines as non-root.
Please change the mode back to make the kernel readable.

I'm confirming this, and marking marking it as medium.
It is fairly common practice to boot kvm or qemu with something like: $(uname -r)
kvm -kernel /boot/vmlinuz-
There are easy workarounds (downloading the kernel and extracting and using it), but they're less than idea.
