Correct. They regularly freeze and maintain their own kernel, merging patches in as needed.
5.15.0-83.94-generic
5.15.0 (mainline kennel version at the point it was frozen)
83.94 (Canonical’s version numbering with newer upstream patches merged in over time)
generic (Canonical maintains several specialized flavors of kernel for different needs)
They’ve recently put out a “HWE” flavor which just starts at a much newer point in the upstream kernel. I’m not sure what the point is in maintaining the 5.15 and the 6.2 flavors side-by-side.
RIP 22.04 LTS. I have like 20+ servers running this.
Pretty sure Ubuntu LTS is completely unaffected by this.
