CVE-2018-16880 (retired)

Priority
Description
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.
Ubuntu-Description
Jason Wang discovered that the vhost net driver in the Linux kernel
contained an out of bounds write vulnerability. An attacker in a guest
virtual machine could use this to cause a denial of service (host system
crash) or possibly execute arbitrary code in the host kernel.
