  - The snapctl component within snapd allows a confined snap to interact with the snapd daemon to take
    certain privileged actions on behalf of the snap. It was found that snapctl did not properly parse
    command-line arguments, allowing an unprivileged user to trigger an authorised action on behalf of the
    snap that would normally require administrator privileges to perform. This could possibly allow an
    unprivileged user to perform a denial of service or similar. (CVE-2024-5138)
