Aha - /usr/lib/virtualbox/VirtualBox is setuid root, and then lowers its privilege to the invoking user, with a pair of setresgid and setresuid calls, prior to the failure to open /proc/self/auxv. Perhaps the auxv file retains its root ownership across these events, which would make it unable to be opened (EPERM) by the non-root invoker.
