Description
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 configurations
• dpdk data plane development kit (>= 18.02.1 < 18.11.10)
• dpdk data plane development kit (>= 19.02 < 19.11.5)
• canonical ubuntu linux 20.04
