Guest triggered use-after-free in Linux xen-netback

ISSUE DESCRIPTION A malicious or buggy network PV frontend can force Linux netback to disable the interface and terminate the receive kernel thread associated with queue 0 in response to the frontend sending a malformed packet. Such kernel thread termination will lead to a use-after-free in Linux...

Kernel: vhost_net: infinite loop while receiving packets leads to DoS

An infinite loop issue was found in the vhostnet kernel module while handling incoming packets in handlerx. The infinite loop could occur if one end sends packets faster than the other end can process them. A guest user, maybe a remote one, could use this flaw to stall the vhostnet kernel thread,...
