Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An issue exists where the jiffies clocksource is utilized during early boot before being registered. This sequence leaves the
max delta raw field at zero, causing the read out to be clamped to a maximum delta of 0, which prevents time from progressing. This was observed in XEN HVM environments, resulting in long boot delays. The problem occurs within the timekeeping init() function.Recommendations
Ensure the jiffies clocksource is initialized before its first usage in the
timekeeping init() function.Exploit
