CVE-2019-3900
A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario.
HIGH 7.7EPSS 4.35%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
