Doc Text:
A flaw was found in malcontent. The newly introduced RecordUsage D-Bus (Desktop Bus) method in malcontent-timerd allows any user on the system to slowly consume disk space in the `/var/lib/malcontent-timerd` directory. This can lead to a Denial of Service (DoS) by exhausting available disk resources, preventing legitimate system operations.
