however, CVE-2017-6264 it address the issue on Android, this CVE does not apply to software in Ubuntu archives.
what’s the issue you’re mentioned? did you meant the upstream kernel fixes?
please refer to JetPack Archive | NVIDIA Developer.
since rel-32 code-line it’s quite old, and it doesn’t support with the latest Jetson platforms.
so… I don’t have solid release date about next rel-32 code-line update.
It’s a shame that NVIDIA abandoned the software support for Jetson Nano before it’s EOL.
This has led my company to decide to move away from Tegra processors for future products.
