Lenovo G series Laptops - any Target availability for Meltdown & Spectre firmware patches?

2018-01-06, 20:43 PM

We own several Lenovo G series - G50, G70 with Windows x64 8.1.

 

Under the Reading Privileged Memory with a Side Channel
located at
https://support.lenovo.com/au/en/solutions/len-18282
Lenovo Security Advisory: LEN-18282
Potential Impact: Malicious code running locally may be able to observe contents of privileged memory, circumventing expected privilege levels.
Severity: High
Scope of Impact: Industry-wide CVE Identifier: “Spectre” CVE-2017-5753, CVE-2017-5715
“Meltdown” CVE-2017-5754

such G Series seem not listed at all and no Target availability or Link to Update.

 

The step #3 of the Windows Client Guidance for IT Pros to protect against speculative execution side-channel vulnerabilility requires
3. Apply the applicable firmware update that is provided by the device manufacturer.

 

Windows Updates and January 2018 Windows security updates (step#2) are not enough, unfortunately.

 

We are quite worried about the flawed Intel CPUs design and the implications of these security risks.

 

Do you plan to release firmware upgrades for Meltdown & Spectre risks for the G Series, please? Thank you.

 

Do you own a G Serie Laptop? Reply to this thread and click over I have this question too.

I'm replying in order to follow - I have a G50-45 Laptop (type 80E3016QUS) and would like to know when I can expect a BIOS update.

Lenovo G series Laptops - still no Target availability for Meltdown & Spectre firmware patches

2018-01-12, 8:05 AM

Michael222,

that's not a solution. I linked that security bulletin above.

As of today January 12, there is is not a Target availability for G-Series support!

 

Please ask for BIOS updates covering Spectre and Meltdown security risks for your G serie model.

I do not fully understand this, but I do have private and customer data on my machine, so if there is some kind of problem I support it being fixed very quickly.

Specify your Lenovo G series Laptops - any Target availability for Meltdown & Spectre

2018-01-12, 9:34 AM

Hi LevUser,

please specify your G serie model for BIOS/ firmware upgrade.  Windows OS upgrades are not enough.

 

In short, about the risks:

"

Meltdown "basically melts security boundaries which are normally enforced by the hardware." Spectre, meanwhile, "breaks the isolation between different applications" allowing "an attacker to trick error-free programs, which follow best practices, into leaking their secrets."

And what does that actually mean? Essentially, either of these vulnerabilities could be theoretically exploited to steal sensitive data, like passwords, off your computer. Spectre is also a threat to your smartphone, so no escape there."

I have the G50-80 powered by Intel core I5 5200U and running on Windows 10 x64. Please release an update soon to fix the issue.
