During October 2025, cc85nod developed a kernel-level proof-of-concept exploit for the google/security-research repository, targeting a Use-After-Free vulnerability in the Linux kernel’s io_uring subsystem. Leveraging expertise in C programming, kernel exploitation, and vulnerability research, cc85nod engineered a feature that demonstrates privilege escalation by overwriting critical kernel structures. The work included comprehensive setup and documentation for v8CTF challenges, enabling hands-on learning and incident response preparation. By detailing vulnerability pathways and defensive strategies, cc85nod provided valuable insights for future mitigations. The depth of the implementation reflects a strong understanding of system programming and security research within a focused, month-long engagement.
