The 6.6.38 stable kernel update has been
released, without the benefit of the usual review process. It reverts some
BPF changes with patches that do not appear in the mainline (in this form,
at least). “All powerpc and arm64 users of the 6.6 kernel series must
upgrade. Everyone else probably should as well to be safe.“
