What is "Rowhammer Attack Against NVIDIA Chips"?
This is a critical-severity osint alert from Schneier on Security. It covers the affected product family and was flagged for security teams to evaluate.
Am I affected?
Affected technology is listed in the Affected Products section above. If your asset inventory contains any of them, assume in-scope until you can prove otherwise.
How urgent is the response?
Critical: do not wait for your normal patch cycle. Verify exposure today, apply the vendor patch immediately, and add detection rules for any post-exploit indicators.
How do I remediate?
Apply the vendor patch listed in the upstream advisory linked under Sources.
