Overview
Affected versions of this package are vulnerable to Buffer Overflow due to improper cleanup in the probe process. An attacker can cause use-after-free conditions by accessing sysfs or character device nodes that remain registered and point to freed memory after a failed power management setup.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
