Description of problem:
SELinux is preventing gdb from 'read' accesses on the chr_file nvidia0.

*****  Plugin catchall (100. confidence) suggests   **************************

Wenn Sie denken, dass es gdb standardmäßig erlaubt sein sollte, read Zugriff auf nvidia0 chr_file zu erhalten.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen:
# ausearch -c 'gdb' --raw | audit2allow -M my-gdb
# semodule -X 300 -i my-gdb.pp
