Summary:

SELinux is preventing fprintd (fprintd_t) "write" access to device /dev/null.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux has denied the fprintd (fprintd_t) "write" access to device /dev/null.
/dev/null is mislabeled, this device has the default label of the /dev
directory, which should not happen. All Character and/or Block Devices should
have a label. You can attempt to change the label of the file using restorecon
-v '/dev/null'. If this device remains labeled device_t, then this is a bug in
SELinux policy. Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against the selinux-policy
package. If you look at the other similar devices labels, ls -lZ /dev/SIMILAR,
and find a type that would work for /dev/null, you can use chcon -t SIMILAR_TYPE
'/dev/null', If this fixes the problem, you can make this permanent by executing
semanage fcontext -a -t SIMILAR_TYPE '/dev/null' If the restorecon changes the
context, this indicates that the application that created the device, created it
without using SELinux APIs. If you can figure out which application created the
device, please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this application.

Allowing Access:

Attempt restorecon -v '/dev/null' or chcon -t SIMILAR_TYPE '/dev/null'
