Exploitation Probability (EPSS)

Low risk
0.12%

2th percentile - higher than 2% of all known CVEs

Summary

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.

Risk Assessment

An attacker can hijack the device's control flow, potentially leading to arbitrary code execution. This requires the ability to supply a crafted NAND flash image.

Recommendation

Update LevelX to a version containing the fix or avoid mounting untrusted NAND flash images. Verify image integrity before mounting.
