Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A flaw exists in the Linux kernel related to the cpufreq subsystem. Specifically, in cpufreq policy alloc(), an uninitialized completion is called within cpufreq sysfs release() when kobject init and add() fails. This can lead to a crash, such as a page fault occurring in the complete function. The issue arises from attempting to use a completion variable before it has been properly initialized, potentially causing system instability.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
