CVE-2026-89088 (GCVE-0-2026-89088)

Vulnerability from cvelistv5 – Published: 2026-10-16 23:06 – Updated: 2026-10-16 23:06

Title

Parted: parted: denial of service via heap buffer overflow during fat16 resize

Summary

A flaw was found in parted. A heap-based buffer overflow exists in libparted's file system resizing logic when handling FAT16 volumes. By convincing a user or administrator to resize a specially crafted FAT16 file system image with malformed directory metadata, an attacker can trigger an oversized read into a fixed-size memory buffer. This issue causes memory corruption, resulting in an application crash and a denial of service (DoS).

Severity

5.5 (Medium)
