EUVD-2026-41000

FatFs R0.16 and earlier contains a downstream-caller vulnerability pattern associated with FatFs long filename handling. With LFN enabled, fno.fname can be up to 255 characters; many callers copy it into short fixed buffers without bounds checks, causing overflow. This maps to CWE-120 Buffer Copy...

CVE-2026-6685

CVE-2026-6685 refers to an Integer Underflow in FatFs during dirty-sector cache flush when handling fragmented volumes. Affected software is FatFs R0.16 and earlier; the issue arises from an unsigned-subtraction wrap in cache handling (fp->sect vs. sect) during interleaved read/write, which ca...

CVE-2026-6683
