USN-3541-1 addressed 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.
Jann Horn discovered that microprocessors utilizing speculative
execution and branch prediction may allow unauthorized memory
reads via sidechannel attacks. This flaw is known as Spectre. A
local attacker could use this to expose sensitive information,
including kernel memory. This update provides mitigations for the
i386 (CVE-2017-5753 only), amd64, ppc64el, and s390x architectures.
(CVE-2017-5715, CVE-2017-5753)
