NVD Description

Note: Versions mentioned in the description apply only to the upstream virtio-win package and not the virtio-win package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

A flaw was found in virtio-win. The RhelDoUnMap() function does not properly validate the number of descriptors provided by a user during an unmap request. A local user could exploit this input validation vulnerability by supplying an excessive number of descriptors, leading to a buffer overrun. This can cause a system crash, resulting in a Denial of Service (DoS).
