Summary
CVE-2024-56739 affecting package kernel for versions less than 6.6.64.2-1
Details

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.
