Released three months ago, Linux kernel 6.4 has officially reached its End of Life (EOL) status. That means it will no longer receive any updates from the official vendor, including security bugs and fixes. The last maintenance update, Linux 6.4.16, was made available along with the announcement of Linux kernel 6.4 EOL on 13 September 2023.


Some Highlights of Linux Kernel 6.5

  • Wi-Fi 7 Support
  • MIDI 2.0 Support
  • UEFI Unaccepted Memory Support
  • Intel SoundWire ACE2.x Support
  • AMD FreeSync Video Support

Issues with the Linux Kernel 6.4 EOL

When the kernel reaches the end of life, it will stop receiving official support and and no longer be maintained. However, if your distribution still uses the EOL kernel, it does not mean your system is at risk. Your distribution will take care of the Linux kernel and patch the security issues when discovered. But if your Linux operating system has reached the end of life, then it’s a big issue. With no security updates from the distribution vendor, your system and sensitive data are highly susceptible to security vulnerabilities.

You must upgrade to the latest supported OS versions as soon as possible. Or, you can consider using TuxCare’s Extended Lifecycle Support, which provides four years of support after the EOL status with vendor-grade security patches for Ubuntu 16.04, Ubuntu 18.04, CentOS 6, 7, and 8, as well as Oracle Linux 6. This solution also gives you additional time to plan the migration while keeping your system secure with all the security patches.

Final Words

If you are still using Linux kernel 6.4 EOL, it is advised that you should upgrade it to the latest version of Linux kernel 6.5 or other LTS versions. However, you can wait for your Linux distribution to include the latest kernel in the next update.

The rolling-release distributions such as Arch Linux and Manjaro have already included Linux kernel 6.5, while other renowned distributions like Debian and Ubuntu will adopt the new kernel series soon. The upcoming Ubuntu rolling release, Ubuntu 23.10 “Mantic Minotaur,” will also feature Linux kernel 6.5 series.

Lastly, the first release candidate for Linux kernel 6.6 is already available. The final release is expected to arrive at the end of October.
