NVIDIA driver response to CPU speculative side channel vulnerabilities - CVE-2017-5753, CVE-2017-5715, CVE-2017-5754

Bulletin Summary

NVIDIA is providing an initial security update to mitigate aspects of Google Project Zero’s January 3, 2018 publication of novel information disclosure attacks that combine CPU speculative execution with known side channels.

NVIDIA’s core business is GPU computing.

We believe our GPU hardware is immune to the reported security issue. As for our driver software, we are providing updates to help mitigate the CPU security issue.

The vulnerability has three known variants:

  • Variant 1 (CVE-2017-5753): CPU mitigations are provided with the security update included in this bulletin. NVIDIA expects to work together with its ecosystem partners on future updates to further strengthen mitigations for affected CPUs.
  • Variant 2 (CVE-2017-5715): NVIDIA’s initial analysis indicates that NVIDIA software running on affected CPUs may require further updates. NVIDIA expects to work together with its ecosystem partners on this variant.
  • Variant 3 (CVE-2017-5754): At this time, NVIDIA has no reason to believe that NVIDIA software is vulnerable to this variant when running on affected CPUs.

For updates and additional information, actively monitor the NVIDIA Product Security page.

Vulnerability Details

The following sections summarize the vulnerabilities. Descriptions are as published on MITRE and risk assessments follow CVSS.

CVE-2017-5753

Computer systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.

CVSS Base Score: 8.2 CVSS Vector: CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N

CVE-2017-5715

Computer systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.

CVSS Base Score: 8.2 CVSS Vector: CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N

CVE-2017-5754

Computer systems with microprocessors utilizing speculative execution may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis of the data cache.

CVSS Base Score: 7.9 CVSS Vector: CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N

NVIDIA’s risk assessment is based on an average of risk across a diverse set of installed systems and may not represent the true risk of your local installation. NVIDIA recommends consulting a security or IT professional to evaluate the risk of your specific configuration.
