CVE-2020-14377: Canonical Ubuntu Linux

High severity, CVSS 7.1. EPSS: 0.4% chance of exploitation in the next 30 days.

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A complete lack of validation of attacker-controlled parameters can lead to a buffer over read. The results of the over read are then written back to the guest virtual machine memory. This vulnerability can be used by an attacker in a virtual machine to read significant amounts of host memory. The highest threat from this vulnerability is to data confidentiality and system availability.

Affected products

• Canonical Ubuntu Linux: version 20.04 only
• Dpdk Data Plane Development Kit: from 18.02.1, before 18.11.10 (fixed in 18.11.10); from 19.02, before 19.11.5 (fixed in 19.11.5)
• Opensuse Leap: version 15.1 only; version 15.2 only
