What to do
AI-suggested
A fix has been implemented in the Linux kernel to add automatic cleanup of the ECC engine on probe failure and device removal. Users should update to the fixed kernel version once available. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's MediaTek SNFI SPI driver was addressed by ensuring proper cleanup of the ECC engine registration on probe failure and device removal. The issue involved missing teardown of the NAND ECC engine, which could lead to resource mismanagement.
