CVE-2026-80686

Description In the migrate vma collect pmd() function, the pte pfn() and pte dirty() functions may be called on non-present Page Table Entries (PTE), such as device-private entries. Because these functions have undefined behavior when operating on non-present entries, this can result in system crashes or incorrect dirty folio accounting.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
