Permission denied on /dev/null for nginx user

[tntrex]

/dev/null file seems bit weird in spaceonfire/nginx-php-fpm image:

bash-5.0$ ls -la /dev/null 
-rw-r--r--    1 root     root          1175 Sep 25 18:14 /dev/null

when same command in php:fpm-alpine image has different output:

/var/www/html # ls -la /dev/null 
crw-rw-rw-    1 root     root        1,   3 Sep 25 18:16 /dev/null
