Hey - I've left some high level feedback:

• Since the same INET{6}_ESPINTCP options are being toggled across multiple defconfigs, consider centralizing this as a shared config fragment or a documented helper so it’s easier to keep all architectures in sync when the mitigation is eventually reverted.
• Because this is a temporary mitigation for CVE-2026-46300, it may be useful to add a brief comment near the disabled config options in each defconfig indicating the CVE and that they should be reconsidered once an upstream fix is available.
