Repeated kernel warnings via unsupported ECC status callback
Published Jan 8, 2025 · Updated May 11, 2026
Incorrect ECC handling in Linux 6.7 through 6.12.3 allows local users to trigger repeated kernel warnings on affected Winbond SPI-NAND chips. The Winbond SPI-NAND table assigns get_status to four one-bit-ECC devices, so the core queries an unsupported corrected-bitflip count instead of relying on standard status bytes. The affected state requires a W25N512GW, W25N01GW, W25N01JW, or W25N02JW device and a corrected bit flip; each such event emits a warning, with no reported data disclosure or modification.
