CVE-2024-3446: Red Hat Enterprise Linux 6

High severity, CVSS 8.2. EPSS: 0.3% chance of exploitation in the next 30 days.

A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within the context of the QEMU process on the host.
