In the Linux kernel, the following vulnerability has been resolved:
rtc: check if _rtcreadtime was successful in rtctimerdowork()
If the _rtcreadtime call fails,, the struct rtctime tm; may contain uninitialized data, or an illegal date/time read from the RTC hardware.
When calling rtctmtoktime later, the result may be a very large value (possibly KTIMEMAX). If there are periodic timers in rtc->timerqueue, they will continually expire, may causing kernel softlockup.
