A configuration that will enable this bug is: # auditctl -a exit,always -S open No privilege whatsoever is required to trigger the OOPS. It's possible that this can be extended to more than just a DoS -- with some care and willingness to exploit timing attacks, this is a read of arbitrary single bits in kernel memory. --Andy
