Summary
Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware platforms. The virt:rhel module contains packages which provide user-space components used to run virtual machines using KVM. The packages also provide APIs for managing and interacting with the virtualized systems.
Security Fix(es):
* QEMU: hcd-ehci: DMA reentrancy issue leads to use-after-free (CVE-2021-3750)
* QEMU: net: triggerable assertion due to race condition in hot-unplug (CVE-2023-3301)

Triggerable assertion due to race condition in hot-unplug
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 de…
