Description

This security bulletin contains information about 1 security vulnerability.


1) Double free (CVE-ID: CVE-2024-3446)

The vulnerability allows a malicious guest to escalate privileges on the system.

The vulnerability exists due to a boundary error in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. A malicious guest can trigger a double free error and execute arbitrary code within the context of the QEMU process on the host.
