Phison PS3111-S11 controller firmware versions through SBFQT1.3 expose privileged vendor unique commands over the ATA interface with absent or defeatable authentication mechanisms. Attackers can bypass the weak CRC-16 based unlock handshake or exploit builds with no VUC lock to read and write controller memory and raw flash, persisting implants across power cycles.
