With security vulnerabilities, you don't give the agent the ability to modify the potentially vulnerable software, naturally. Instead you make them do what an attacker would have to do: come up with an input that, when sent to the unmodified program, triggers the vulnerability.

How do you know if it triggered the vulnerability? Luckily for low-level memory safety issues like the ones Sean (and o3) found we have very good oracles for detecting memory safety, like KASAN, so you can basically just let the agent throw inputs at ksmbd until you see something that looks kind of like this: https://groups.google.com/g/syzkaller/c/TzmTYZVXk_Q/m/Tzh7SN...
