CVE-2026-68092

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> time/jiffies: Register jiffies clocksource before usage<br /> <br /> Teddy reported that a XEN HVM has a long boot delay, which was bisected to<br /> the recent enhancements to the negative motion detection. It turned out<br /> that the jiffies clocksource is used in early boot before it is registered,<br /> which leaves the max_delta_raw field at zero. That causes the read out to<br /> be clamped to the max delta of 0, which means time is not making progress.<br /> <br /> Cure it by ensuring that it is initialized before its first usage in<br /> timekeeping_init().
