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