6.0 (Medium) CVSS_V3 - CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H CVSS Calculator

Summary

[none]

Details

A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device in versions prior to 6.1.0. The issue occurs while handling a "PVRDMAREGDSRHIGH" write from the guest and may result in a crash of QEMU or cause undefined behavior due to the access of an uninitialized pointer. The highest threat from this vulnerability is to system availability.
