parted: A flaw was found in parted
CVE-2026-89088 is fixed in 4 products on 1 platform, first by DEBIAN-CVE-2026-89088, released October 1, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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).
