CVE-2026-63861
Description
A flaw was found in the Linux kernel's mtk-snfi (MediaTek SPI NAND Flash Interface) driver. The mtk_snand_probe() function, responsible for registering the on-host NAND Error Correcting Code (ECC) engine, did not properly unregister the engine during probe failures or device removal. This oversight could lead to improper resource management within the kernel, potentially causing system instability or resource exhaustion.
