Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.1.82
Description
The Linux kernel mtd subsystem, specifically the STM32 FMC2 NAND controller, contained a flaw where overlapping mappings could occur on the ECC buffer. This issue was addressed by utilizing a contiguous non-cacheable buffer to prevent these overlaps. The issue manifested as DMA-API errors and warnings during operation, potentially leading to system instability.
Recommendations
Update to Linux kernel version 6.1.82 or later.
