| CVE | Severidad | EPSS | Explotación activa | Publicada | Descripción |
|---|---|---|---|---|---|
| CVE-2026-6688 | Alta (7.6) | 0.32% | — | 1 jul 2026 | 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… |
| CVE-2026-6687 | Alta (7.6) | 0.35% | — | 1 jul 2026 | FatFs R0.16 and earlier contains a stack overflow bug in f_getlabel() because exFAT label length (XDIR_NumLabel) is trusted without enforcing spec maximums. This maps to CWE-121 (Stack-based Buffer Overflow). Estimated… |
| CVE-2026-6686 | Media (4.6) | 0.26% | — | 1 jul 2026 | FatFs R0.16 and earlier contains an uninitialized cluster exposure when f_lseek() extends files beyond EOF without zero-filling newly allocated clusters. This maps to CWE-908 (Use of Uninitialized Resource). Estimated… |
| CVE-2026-6684 | Media (4.6) | 0.31% | — | 1 jul 2026 | FatFs prior to R0.16 that use GPT scanning with 'FF_LBA64 = 1' contains an issue where an unbounded loop count derived from GPT header field GPTH_PtNum, enabling extremely long or effectively infinite mount-time scans.… |
| CVE-2026-6683 | Media (4.6) | 0.31% | — | 1 jul 2026 | FatFs R0.16 and earlier contains a divide-by-zero in exFAT sync logic bug when crafted metadata causes n_fatent - 2 to be zero during write/sync operations. This maps to CWE-369 (Divide By Zero). Estimated CVSS v3.1… |
| CVE-2026-6682 | Alta (7.6) | 0.32% | — | 1 jul 2026 | In FatFS R0.16 and earlier contains a FAT32 integer overflow bug in mount_volume() where fasize *= fs->n_fats can wrap, leading to attacker-controlled file-size metadata and unsafe read lengths in downstream callers.… |
