:SELinux is preventing /usr/bin/bash from using the 'dac_override' capabilities.
:*****  Plugin dac_override (91.4 confidence) suggests  ***********************
:If você deseja ajudar a identificar se o domínio precisa deste acesso ou se você possui um arquivo com as permissões erradas em seu sistema.
:Then ligue a auditoria completa para obter informações de caminho sobre ofender arquivo e gerar um erro novamente.
:Ligue auditoria completa
:# auditctl -w /etc/shadow -p w
:Tente recriar o AVC. Depois execute
:# ausearch -m avc -ts recent
:Caso você veja a memória PATH verifique a propriedade ou permissões no arquivo e repare-o, caso contrário reporte como um bugzilla.
:*****  Plugin catchall (9.59 confidence) suggests  ***************************
:If você acredita que o bash deva ser permitido a capacidade de dac_override  por default.
:Then você precisa reportar este como um erro.
:Você pode gerar um módulo de política local para permitir este acesso.
:permitir este acesso agora executando:
:# grep sh /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
