Next-Gen Exploitation: Exploring The PS5 Security Landscape
summary
Compares PS4-era chains (USB xattr truncation leading to kernel OOB and full jailbreak via a crafted USB image) with PS5’s tightened model: enforced SMAP and SMEP, kernel CFI, and execute-only memory backed by an AMD hypervisor using nested paging and a small set of hypercalls (about 14 hypercalls). Shows a working WebKit→blind kernel exploit path for one firmware using a kernel dump and brute‑forced gadgets, explains MP0/MP3/A53 secure coprocessors, and argues future work targets data‑only mailbox hijacks and VM‑escape vectors.
