Note

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

  • Amazon Linux stopped 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 Amazon Linux 2023.
