Description
Mounting an attacker-controlled NAND flash image (`lx_nand_flash_open()`) triggers an unbounded out-of-bounds heap **write** in LevelX's NAND flash-translation-layer metadata parser that overwrites a driver function pointer in the control block, giving a demonstrated control-flow hijack — RIP set to a full 8-byte attacker-chosen value (register-verified). Two accompanying OOB reads. All reproduced verbatim under ASan at HEAD `9f1cfdc`. (The affected metadata-parser header states "Some portions generated by Copilot (Sonnet 4.6)" — an AI-generated parser with an unchecked on-flash count.)
Affected products
- Eclipse Foundation eclipse-threadx/levelx(NAND driver): HEAD `9f1cfdc` and prior; Finding 1 introduced by commit `47b2a17d`; Finding 2 is the un-patched half of the Nov-2025 fix `0f7dd521`.
