Details

USN-3597-1 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.

USNS 3541-2 and 3523-2 provided mitigations for Spectre and Meltdown
(CVE-2017-5715, CVE-2017-5753, CVE-2017-5754) for the i386, amd64,
and ppc64el architectures for Ubuntu 16.04 LTS. This update provides
the corresponding mitigations for the arm64 architecture. Original
advisory details:

Jann Horn discovered that microprocessors utilizing speculative execution
and indirect branch prediction may allow unauthorized memory reads via
sidechannel attacks. This flaw is known as Meltdown. A local attacker could
use this to expose sensitive information, including kernel memory.
(CVE-2017-5754)
