Summary
linux-hwe vulnerability
Details
USN-3484-1 fixed vulnerabilities in the Linux kernel for Ubuntu 17.04. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 17.04 for Ubuntu 16.04 LTS.
It was discovered that the KVM subsystem in the Linux kernel did not properly keep track of nested levels in guest page tables. A local attacker in a guest VM could use this to cause a denial of service (host OS crash) or possibly execute arbitrary code in the host OS.
