Ubuntu Linux kernel cho NVIDIA Tegra: kiểm tra hệ thống và áp dụng cập nhật bảo mật

Ubuntu đã công bố cảnh báo USN-9091-1 về nhiều lỗ hổng trong Linux kernel dành cho NVIDIA Tegra. Hãy đối chiếu thông tin trong thông báo bảo mật Ubuntu để xác định gói cập nhật liên quan trước khi kết luận hệ thống đã được khắc phục.

Tổng quan và thông tin kỹ thuật

Linux kernel là lõi hệ điều hành, quản lý phần cứng và cung cấp dịch vụ nền tảng cho phần mềm. USN-9091-1 cảnh báo nhiều lỗ hổng trong kernel dành cho NVIDIA Tegra; hồ sơ đầu vào không mô tả cơ chế khai thác hay tác động cụ thể của từng lỗ hổng.

Phạm vi ảnh hưởng

Đối tượng cần rà soát là các hệ thống Ubuntu sử dụng Linux kernel NVIDIA Tegra. Hồ sơ không cung cấp nhánh phiên bản bị ảnh hưởng hoặc phiên bản đã vá, vì vậy cần đối chiếu gói và phiên bản thực tế với thông tin cập nhật trong thông báo Ubuntu.

Kiểm tra hệ thống

1. Xem phiên bản kernel đang chạy:

   Sao chép lệnh

   uname -r

2. Liệt kê các gói kernel đã cài để xác định gói NVIDIA Tegra liên quan:

   Sao chép lệnh

   dpkg-query -W 'linux-image*'

3. Đối chiếu gói và phiên bản đã cài với thông tin gói được cập nhật trong USN-9091-1. Nếu chưa xác định được phiên bản đã vá, tra cứu thông báo Ubuntu trước khi kết luận.

Khắc phục và giảm thiểu

1. Ưu tiên xác định gói kernel đang sử dụng và đối chiếu thông tin cập nhật trong USN-9091-1.

2. Khi xác định được gói cập nhật bảo mật phù hợp, áp dụng bản cập nhật đó. Hồ sơ đầu vào không cung cấp phiên bản gói đã vá hoặc hướng dẫn cập nhật cụ thể.
