Title
spi: mtk-snfi: unregister ECC engine on probe failure and remove() callback
Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: mtk-snfi: unregister ECC engine on probe failure and remove() callback
mtk_snand_probe() registers the on-host NAND ECC engine, but teardown was
missing from both probe unwind and remove-time cleanup. Add a devm cleanup
action after successful registration so
nand_ecc_unregister_on_host_hw_engine() runs automatically on probe
failures and during device removal.
Severity
No CVSS data available.
