CVE-2026-46277

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

Description An issue exists in the mm/zone device component where the system accesses a device folio after the folio free() function has been called. Because a folio can be immediately reallocated by a driver with a different order, its contents may change. The flaw occurs when the system attempts to extract the pgmap from the folio instead of using a local stack variable during the percpu ref put many() function call.

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