CVE-2026-89085

A flaw was found in parted. A heap-based buffer overflow can occur when processing a specially crafted FAT32 filesystem due to an integer calculation error during buffer allocation. A local attacker could exploit this by enticing a user or automated service to open a malicious filesystem image, resulting in an application crash leading to a Denial of Service (DoS) or potential memory corruption.
