Overview
Affected versions of this package are vulnerable to Improper Access Control due to improper handling of the key_set_expiry process. An attacker can prevent intended expiration of keys by exploiting the unconditional overwrite of key expiration during instantiation, which may result in keys becoming permanent and disrupt processes relying on key expiry, such as DNS updates.
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
