Ubuntu Security Notice 3903-2 - USN-3903-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.10. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 18.10 for Ubuntu 18.04 LTS. 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 or possibly execute arbitrary code in the host kernel. Various other issues were also addressed.
