Overview

About vulnerability

In the Linux kernel, the following vulnerability has been resolved:

mm/hugetlb: do not dissolve gigantic pages without runtime support

dissolve_free_hugetlb_folio() doesn’t check hstate_is_gigantic_no_runtime(h) though remove_hugetlb_folio()/ update_and_free_hugetlb_folio() silently bail for such folios, so it frees a still-listed folio and, on vmemmap restore failure, the add_hugetlb_folio() rollback corrupts the free list.

Affected packages:
kernel @ 5.14.0 (+2 more)
