Name of the Vulnerable Software and Affected Versions QEMU (affected versions not specified)

Description A double free vulnerability was found in QEMU virtio devices, including virtio-gpu, virtio-serial-bus, and virtio-crypto. The mem reentrancy guard flag does not sufficiently protect against DMA reentrancy issues, which 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.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
