CVE-2019-3900 | BDVDB-2026-115739 Detail
Red HatKernel
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.
Impact#
Per CVSS v3.0: confidentiality impact none, integrity impact none, availability impact high. Attack vector: network.
