CVE-2026-89967

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An out-of-bounds write occurs in the migrate device range() and migrate device pfns() functions. This happens when a compound folio extends beyond the end of the range provided by the caller, causing the loops to clear following folio entries without limiting them to the available slots in the npages-sized array. A compound folio is a memory management structure that groups multiple contiguous physical pages together to reduce overhead.

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