URL: https://github.com/apache/nuttx/pull/19611

   ## Summary
   
   Reading /proc/<pid>/group/env for another task dereferenced tg_envp under 
the caller's own address environment instead of the target task's, since 
tg_envp lives in the target's user heap. Switch to the target's address 
environment around the traversal, and to the caller's own environment only 
around the copy into the caller's buffer.
   
   ## Impact
