      "title": "mm/mseal: update VMA end correctly on merge",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm/mseal: update VMA end correctly on merge\n\nPreviously we stored the end of the current VMA in curr_end, and then upon\niterating to the next VMA updated curr_start to curr_end to advance to the\nnext VMA.\n\nHowever, this doesn't take into account the fact that a VMA might be\nupdated due to a merge by vma_modify_flags(), which can result in curr_end\nbeing stale and thus, upon setting curr_start to curr_end, ending up with\nan incorrect curr_start on the next iteration.\n\nResolve the issue by setting curr_end to vma->vm_end unconditionally to\nensure this value remains updated should this occur.\n\nWhile we're here, eliminate this entire class of bug by simply setting\nconst curr_[start/end] to be clamped to the input range and VMAs, which\nalso happens to simplify the logic.",
