OK, I think I figured it out.

In mm-hotfixes-unstable I have

kho-fix-out-of-bounds-access-of-vmalloc-chunk.patch
kho-fix-unpreservation-of-higher-order-vmalloc-preservations.patch
kho-warn-and-exit-when-unpreserved-page-wasnt-preserved.patch

The first two are applicable to 6.18-rcX and the third is applicable to
6.18-rcX, with a cc:stable for backporting.
