SELinux is preventing /usr/bin/passwd from write access on the file
/root/test.
***** Plugin leaks (86.2 confidence) suggests *****************************
If you want to ignore passwd trying to write access the test file,
because you believe it should not need this access.
Then you should report this as a bug.
You can generate a local policy module to dontaudit this access.
Do
ausearch -x /usr/bin/passwd --raw | audit2allow -D -M my-passwd
semodule -X 300 -i my-passwd.pp

如果上一步中的输出没有包含清晰的建议:
启用全路径审核查看访问对象的完整路径,并让其他 Linux Audit 事件字段可见:
auditctl -w /etc/shadow -p w -k shadow-write
# auditctl -w /etc/shadow -p w -k shadow-write
