Linux · Linux Kernel · CVE-2024-56739
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
The issue concerns the Linux kernel, where the `rtc timer do work()` function may process uninitialized data or an illegal date/time read from the RTC hardware if the ` rtc read time` call fails. This can lead to a very large value (possibly `KTIME MAX`) when calling `rtc tm to ktime` later. As a result, periodic timers in `rtc->timerqueue` may continually expire, potentially causing a kernel softlockup.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
