CVE ID : CVE-2026-24708
Published : Feb. 18, 2026, 6:24 p.m. | 1 hour, 38 minutes ago
Description : 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.
Severity: 8.2 | HIGH
