CVE-2026-24708 is a high-severity vulnerability affecting OpenStack Nova versions before 30.2.2, 31.2.1, and 32.1.1, specifically impacting compute nodes configured with the Flat image backend (use_cow_images=False). A malicious user can craft a QCOW header on a disk, triggering an unsafe image resize operation via qemu-img without format restrictions, potentially leading to data destruction on the host system. With a CVSS score of 8.2 (HIGH), this vulnerability has a network attack vector and high attack complexity, allowing a low-privileged attacker to achieve high integrity and availability impact. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
