A flaw was found in the Linux kernel’s handle_rx() function in the
[vhost_net] driver. A malicious virtual guest, under specific conditions,
can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host
which may lead to a kernel memory corruption and a system panic. Due to the
nature of the flaw, privilege escalation cannot be fully ruled out.
Versions from v4.16 and newer are vulnerable.
