USNS 3541-1 and 3523-1 provided mitigations for Spectre and Meltdown
(CVE-2017-5715, CVE-2017-5753, CVE-2017-5754) for the i386, amd64,
and ppc64el architectures in Ubuntu 17.10. 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.
