Summary
USN-3522-1 fixed a vulnerability in the Linux kernel to address
Meltdown (CVE-2017-5754). Unfortunately, that update introduced
a regression where a few systems failed to boot successfully. This
update fixes the problem.
We apologize for the inconvenience.
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.
