CVE-2026-6686

FatFs R0.16 and earlier contains an uninitialized cluster exposure when flseek extends files beyond EOF without zero-filling newly allocated clusters. This maps to CWE-908 Use of Uninitialized Resource. Estimated CVSS v3.1 vector: CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N 4.6, Medium. The...

CVE-2026-6686

FatFs CVE-2026-6686 affects FatFs R0.16 and earlier. The issue is an uninitialized cluster exposure when f_lseek() extends a file beyond EOF without zero-filling newly allocated clusters, mapping to CWE-908 (Use of Uninitialized Resource). The root cause is not zero-filling or initializing cluste...

UBUNTU-CVE-2018-7167

Calling Buffer.fill or Buffer.alloc with some parameters can lead to a hang which could result in a Denial of Service. In order to address this vulnerability, the implementations of Buffer.alloc and Buffer.fill were updated so that they zero fill instead of hanging in these cases. All versions of...
