Name of the Vulnerable Software and Affected Versions cloud-init (affected versions not specified)

Description The issue concerns the cloud-init packages, which provide init scripts for cloud instances to handle tasks like retrieving and installing SSH keys and running user scripts. A problem arises when cloud-init writes route6-$DEVICE config with a HEX netmask, which is not compatible with the ip route command. This incompatibility results in an error, as the ip route command expects an inet6 prefix rather than a HEX netmask.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
