What is CVE-2022-24986?

KDE KCron versions up to 21.12.2 exhibit a significant security flaw due to improper file handling practices. When KCron saves files, it utilizes a temporary file in the /tmp directory and reuses the same filename across different editing sessions. As a result, an attacker could potentially monitor the file's creation and, during a subsequent session, exploit the reused filename to intercept and manipulate the data. This vulnerability could allow unauthorized command execution if an attacker can access this temporary file, thereby compromising the system's integrity.
