Re: Patches for Meltdown and Spectre cpu flaws

From my unattended-upgrades this morning

2018-01-05 06:44:48,034 INFO Packages that will be upgraded: linux-image-amd64
2018-01-05 06:44:48,035 INFO Writing dpkg log to '/var/log/unattended-upgrades/unattended-upgrades-dpkg.log'

Possibly already done!

Re: Patches for Meltdown and Spectre cpu flaws

Debian has released a security update DSA-4078-1 addressing the bugs above, see https://www.debian.org/security/2018/dsa-4078

Debian wrote:

... This specific attack has been named Meltdown and is addressed in the Linux kernel for the Intel x86-64 architecture by a patch set named Kernel Page Table Isolation, enforcing a near complete separation of the kernel and userspace address maps and preventing the attack. This solution might have a performance impact, and can be disabled at boot time by passing pti=off to the kernel command line. ...
