CVE-2017-7472

This PoC exploits a memory consumption vulnerability in the Linux kernel's KEYS subsystem by repeatedly calling keyctl_set_reqkey_keyring, leading to a denial of service (DoS). The code is a minimal reproducer that triggers the vulnerability by exhausting kernel memory.

This exploit triggers a memory leak in the Linux kernel by repeatedly calling keyctl_set_reqkey_keyring, causing the system to run out of memory. It leverages a vulnerability in the key management subsystem.
