dev/null vulnerability

[linuxh8ter]

Hi,
I believe I have found a vulnerability in dev/null.
I first came upon it, when I was writing an email, and I saved the file at the location /dev/null. Upon logging in again, I found that the file has mysteriously vanished. This was very sensitive information, so I even encrypted it. But this seem like a vulnerability in the Linux kernel, that non root users have access to delete and modify /dev/null as it is the only possible explanation for my file disappearing.

My dmesg follows
