Summary
linux-hwe, linux-azure, linux-gcp, linux-oem vulnerability
Details

USN-3548-1 fixed vulnerabilities in the Linux kernel for Ubuntu 17.10. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 17.10 for Ubuntu 16.04 LTS.

Jay Vosburgh discovered a logic error in the x86-64 syscall entry implementation in the Linux kernel, introduced as part of the mitigations for the Spectre vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.
