CVE-2019-3900

HIGH

Linux Kernel < 3.16.72 - Infinite Loop

Title source: rule
STIX 2.1

Description

An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario.
