CVE-2023-3301 (GCVE-0-2023-3301)

Vulnerability from cvelistv5 – Published: 2023-09-13 16:09 – Updated: 2025-02-13 16:55

Title

Triggerable assertion due to race condition in hot-unplug

Summary

A flaw was found in QEMU. The async nature of hot-unplug enables a race scenario where the net device backend is cleared before the virtio-net pci frontend has been unplugged. A malicious guest could use this time window to trigger an assertion and cause a denial of service.

Severity

5.6 (Medium)
