Is there any security risks with files in /proc/<PID>/attr/ globally readable and writeable?

Issue

Root owned files under /proc/1/attr seem to be world readable :

-rw-rw-rw-  1 root root 0 Mar 19 09:17 /proc/1/task/1/attr/current 
-rw-rw-rw-  1 root root 0 Mar 19 09:17 /proc/1/task/1/attr/exec 
-rw-rw-rw-  1 root root 0 Mar 19 09:17 /proc/1/task/1/attr/fscreate 
-rw-rw-rw-  1 root root 0 Mar 19 09:17 /proc/1/attr/current 
-rw-rw-rw-  1 root root 0 Mar 19 09:17 /proc/1/attr/exec 
-rw-rw-rw-  1 root root 0 Mar 19 09:17 /proc/1/attr/fscreate 
-rw-rw-rw-  1 root root 0 Mar 19 09:17 /proc/2/task/2/attr/current 

Wouldn't this be a security risk?
