CVE-2026-89085

6.6 MEDIUM 0.2% exploit odds No fix listed Memory safety

What it is

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.

At a glance

Exploitability: Can be exploited locally on the machine without logging in, but needs a user to act. High risk of service disruption.
Exploit odds: 0.2% chance of exploitation in the next 30 days (EPSS).
Fix: No patch or advisory is linked yet. Look at mitigations or restrict exposure.
