Random reboots are occurring on PC’s with newer Intel
processors after the update for protection against the Spectre CPU flaw. Intel
have conducted tests and found that the random reboots are affecting its new
processors as well as its older chips.
Intel found that systems had an increase in unwanted reboots
after the firmware related update relating to the Spectre issue was installed
on systems with Skylake, Sandy Bridge, Ivy Bridge and Kaby Lake architecture. They’ve
advised computer manufacturers to stop offering the Spectre firmware update
despite the side effects. Intel have also said however that administrators in
datacentres should assess the risk of an exploit by Spectre against the cost of
Hackers could bypass system protections on many devices due
to the Meltdown and Spectre design flaws in CPU’s which means sensitive
information such as passwords could be read. The update that causes the random
reboots was released to prevent attacks that use Branch Target Injection to
exploit the Spectre vulnerability.
New beta firmware updates are to be released by Intel to
system vendors which are to be validated this week. Patches for the Spectre and
Meltdown vulnerability will be released separately.
Server performance will also be severely decreased due to
the Spectre update as discovered by Intel.
