rmgp-complete-handoff

Complete workspace + experiment-state backup for the CVE-2026-43499 (RMGP / "popsicle") exploit targeting SM-A376B / Exynos S5E8845 / A376BXXU1AZB7.

Read CURRENT_STATE.md first — it is the authoritative "where we are" note: what works (slide, skb leak, pipe oracle, 1st KernelSnitch pass / fops page MATCH), what is blocked (2nd KernelSnitch pass / pipe buffer page leak), the exact fix applied, the exact build/run commands, and the precise point where the live test was stopped (prepare_kernel_page retry 1/8, scan frozen at 130000/131072 in logs/run9.log).

Layout

• RMGP/ — full patched source tree (builds as-is)
• selftest/ — a37-final.so (built binary), fh.bin, vhash.py, difftest.py
• logs/ — full experiment record (run2.log..run9.log, adb.0.log, probe2.log)
• reference/REFERENCE_REPOS.txt — manifest of upstream clones (not copied)
• ORIGINAL_RMGP_HISTORY.bundle — full original git history (git clone to restore)
• CURRENT_STATE.md — the handoff note
