Vulnerability from csaf_certbund - Published: 2021-06-17 22:00 - Updated: 2024-09-02 22:00Es existiert eine Schwachstelle in QEMU, welche aufgrund einer fehlerhaften Implementierung von VMWare's paravirtuellen RDMA besteht und auf eine fehlende Überprüfung von Eingaben durch ein Gast-System zurückzuführen sind. Ein lokaler Angreifer im Gast-System kann diese Schwachstelle ausnutzen, um einen Denial of Service Zustand herbeizuführen.

Es existiert eine Schwachstelle in QEMU, welche aufgrund einer fehlerhaften Implementierung von VMWare's paravirtuellen RDMA besteht und beim Verarbeiten einer "PVRDMA_REG_DSRHIGH" Schreiboperation des Gast-Systems auftritt. Ein lokaler Angreifer im Gast-System kann diese Schwachstelle ausnutzen, um einen Denial of Service Zustand herbeizuführen.
