Issue

• When reading /proc/$PID/environ, Permission denied is received even though process is owned by the user trying to read, and file permissions indicate it can read the file

  $ ls -l /proc/3039/environ
  -r--------. 1 test root 0 May 21 14:02 /proc/3039/environ
  $ id
  uid=500(test) gid=501(test) groups=501(test),10(wheel) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
  $ cat /proc/3039/environ
  cat: /proc/3039/environ: Permission denied
  

• numastat on owned process returns Permission denied

  $ numastat java
