Technical details
An unchecked on-flash count in the NAND flash-translation-layer metadata parser (lx_nand_flash_open function) enables an out-of-bounds heap write that overwrites driver function pointers in the control block, allowing arbitrary code execution. The vulnerability requires attacker control over the NAND flash device image and is triggered during mount/initialization. The parser contains AI-generated code that lacks proper bounds validation on metadata counts.
