VUL-0: CVE-2024-3446: qemu: virtio: DMA reentrancy issue leads to double free vulnerability
Last modified: 2024-07-08 14:14:53 UTC
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 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.
