Note

  • Amazon Linux 2 will reach end of life on June 30, 2026. For more information, see Amazon Linux 2 FAQs.

  • On 2026-01-20, Amazon Linux will update its default kernel from 4.14 to 5.10 for the Amazon Linux 2 base AMI (amzn2-ami-hvm-x86_64-gp2 and amzn2-ami-hvm-arm64-gp2), reflecting our long-standing recommendation that all AL2 customers use kernel 5.10 as their default

    • This means that customers launching new EC2 instances using these standard AMI names will automatically receive kernel 5.10, benefiting from enhanced performance, security improvements, and better hardware support without requiring any explicit action.

  • Amazon Linux will end live patching for AL2 Kernel 4.14 on 2025-10-31. Customers are encouraged to use kernel 5.10 as the default kernel for AL2 or move to AL2023 with kernels 6.1 and 6.12.

  • Amazon Linux will provide live patches for AL2 Kernel 5.10 until the end of life of AL2 on 2026-06-30.

  • We have now added additional SSM parameters to clearly indicate the kernel version installed on the AMIs:

    • kernel-default represents our latest available kernel version (currently kernel-5.10)

    • For AMIs with kernel-5.10, use SSM parameters containing "kernel-5.10" or "kernel-default" in the parameter name (see examples below):

      • /aws/service/ami-amazon-linux-latest/amzn2-ami-kernel-5.10-hvm-x86_64-gp2

      • /aws/service/ami-amazon-linux-latest/amzn2-ami-kernel-default-hvm-x86_64-gp2

    • For AMIs with kernel-4.14, use SSM parameters containing "kernel-4.14" in the parameter name (see example below):

      • /aws/service/ami-amazon-linux-latest/amzn2-ami-kernel-4.14-hvm-x86_64-gp2

  • We strongly recommend that customers migrate to the latest kernel version (kernel-5.10)
