CVE-2026-24708 (GCVE-0-2026-24708)

Vulnerability from cvelistv5 – Published: 2026-02-18 00:00 – Updated: 2026-09-11 12:09

Summary

An issue was discovered in OpenStack Nova before 30.2.2, 31 before 31.2.1, and 32 before 32.1.1. By writing a malicious QCOW header to a root or ephemeral disk and then triggering a resize, a user may convince Nova's Flat image backend to call qemu-img without a format restriction, resulting in an unsafe image resize operation that could destroy data on the host system. Only compute nodes using the Flat image backend (usually configured with use_cow_images=False) are affected.
