Nvidia became the latest chipmaker to release software patches for the Spectre microchip security threat, indicating that the chipset flaw was affecting graphic processors as well as CPUs.
Security researchers last week disclosed the chipset flaws, dubbed Meltdown and Spectre, that could allow hackers to steal passwords or encryption keys on most types of computers, phones and cloud-based servers.
Advanced Micro Devices amd , ARM Holdings, and now Nvidia nvda have reported being exposed to only the Spectre flaw, but Intel has been hit by both.
The affected Nvidia chipsets include GeForce, Tesla, Grid, NVS and Quadro, the company said in a blogpost on Tuesday.
Microsoft msft said Tuesday its software patches slowed down some PCs and servers, with systems running on older Intel intc processors seeing a noticeable decrease in performance.
Meltdown lets hackers bypass the hardware barrier between applications run by users and the computer’s memory, potentially letting hackers read a computer’s memory and steal passwords.
Spectre lets hackers potentially trick otherwise error-free applications into giving up secret information.
Nvidia shares were down 1.6% at $218.49 in premarket trading on Wednesday.
