Vulnerability from github – Published: 2026-05-01 15:30 – Updated: 2026-05-11 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

spi: amlogic: spifc-a4: unregister ECC engine on probe failure and remove() callback

aml_sfc_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 ?

5.5 (Medium)
