CVE-2020-16121
PackageKit provided detailed error messages to unprivileged callers that exposed information about file presence and mimetype of files that the user would be unable to determine on its own.
Does this matter?
Lower severity and a low EPSS score (0.47%). Track it; it rarely justifies an emergency change on its own.
