CVE-2019-0715
Status: ModifiedMedium (5.8)—
A denial of service vulnerability exists when Microsoft Hyper-V Network Switch on a host server fails to properly validate input from a privileged user on a guest operating system. An attacker who successfully exploited the vulnerability could cause the host server to crash. To exploit the vulnerability, an attacker who already has a privileged account on a guest operating system, running as a virtual machine, could run a specially crafted application that causes a host machine to crash. The update addresses the vulnerability by modifying how virtual machines access the Hyper-V Network Switch.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:N/I:N/A:H
- Base score: 5.8
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 5.00%
- Percentile among all scored CVEs: 92
- Score date: 10/9/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
