Local privilege escalation on Xiaomi MiTV4 (Amlogic S905L2, Mali-400 Utgard r6p1). Amlogic's published driver compiles out the physical-address validation, so userspace gets arbitrary physical writes: GPU write-back -> unused sys_call_table slots -> kallsyms resolver -> memcpy -> SELinux off. Verified; no CVE claimed. Prior art: lr-m/RIPMaliUtgard
