CVE-2022-1050

Es existiert eine Schwachstelle in QEMU. Diese besteht in der QEMU-Implementierung des paravirtuellen RDMA-Geräts von VMWare. Über einen manipulierten Gasttreiber können HW-Befehle ausgeführt werden, wenn gemeinsam genutzte Puffer noch nicht zugewiesen sind, was zu einem Use-after-free-Zustand führt. Ein Privilegierter Angreifer kann diese Schwachstelle ausnutzen, um Code zur Ausführung zu bringen.
