err no. outside of rarely used acl systems basic unix/linux permissions are far less granular than the windows equivalents. For desktops modern windows handles things very similarly to modern linux, which is to say that you don't run as "root" or "administrator" by default and programs request escalated privileges via sudo on linux and UAC on windows. As to privesc vulns, most desktop linux distros have limited protections there. One kernel bug can see someone escalate from user to root fairly easily. With modern Windows apps there is at least a sandbox in play, so that a sandbox escape is required in addition to the kernel bug. Both Operating systems can be configured to be more secure of course...
