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.

The vulnerability has three known variants:

- Variant 1 (CVE-2017-5753): 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.

- Variant 2 (CVE-2017-5715): NVIDIA’s initial analysis indicates that the NVIDIA GPU Display Driver is potentially affected by this variant. NVIDIA expects to work together with its ecosystem partners on future updates for this variant.
