Hello, I found a very serious security flaw in the testing version, this is an unacceptable flaw.

The 5.10.36 kernel files are exposed to being modified without super user permissions, because the user is assigned as owner and group instead of root, leaving the entire kernel to any modification or attack without the need to use even sudo.

This is caused by totally careless packaging, and it shows that they don't know how to pack and they don't know about safety.

Many packages in the store have the same problem, they are poorly packaged and application files can be modified and attacked without any hindrance, without using sudo or needing super user permissions.

This makes Deepin extremely insecure, vulnerable and easy to attack, these bad practices weaken or rather completely destroy the security mechanisms of GNU / Linux.

It is urgent and very important that they learn to pack correctly as soon as possible, and that these safety problems be corrected immediately.

You can check the compromised files with the following command 

LIST="/boot /etc /mnt /opt /srv /usr"; FAILS=$(for FOLDER in $LIST; do find $FOLDER -user $(whoami) 2>/dev/null; done;); if [[ $FAILS ]]; then ls -l $FAILS; fi

I attach the files with the results on my computer
