| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
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.
Exploit
Use of Uninitialized Resource
Improper Locking
