An issue was discovered in xenoprof in Xen through 4.13.x, allowing guest
OS users (without active profiling) to obtain sensitive information about
other guests. Unprivileged guests can request to map xenoprof buffers, even
if profiling has not been enabled for those guests. These buffers were not
scrubbed.
