CVE-2026-93284

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

Description An issue exists in the drm/pagemap component where drm pagemap migrate unmap pages() relies on a pages array to identify pages requiring DMA unmapping. Because drm pagemap migration unlock put pages() clears this array during cleanup, calling drm pagemap migrate unmap pages() afterward results in a loss of valid page information.

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