These can happen at arbitrary points in time, i.e. while in timer_read(), which pushes time forward just a little bit. Then, if we happen to get the interrupt after calculating the new time to push to, but before actually finishing that, the interrupt will set the time to a value that&#39;s incompatible with the forward, and we&#39;ll crash because time goes backwards when we do the forwarding.</p> <p>Fix this by reading the time_travel_time, calculating the adjustment, and doing the adjustment all with interrupts disabled.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>um: time-travel: fix time corruption</p> <p>In &#39;basic&#39; time-travel mode (without =inf-cpu or =ext), we still get timer interrupts.
