Couldn’t find whether this even impacts LTS builds. Either way, seems like patching should resolve the issue
LTS uses the 5.15 Linux kernel (by default). This vulnerability impacts 6.2.
If I understand correctnly… Ubuntu 22.04.2 LTS has 5.19 kernel by default: https://9to5linux.com/ubuntu-22-04-2-lts-released-with-linux-kernel-5-19-updated-components “the Ubuntu 22.04.2 LTS point release also comes with a newer kernel, namely Linux 5.19, from the Ubuntu 22.10 (Kinetic Kudu) release”
As you said, if it is only 6.2, still out of the window.
