CVE-2026-74482

A flaw was found in the Linux kernel's huge memory management mm/hugememory. A race condition exists in the foliosplit function where the immaprwsem lock is released prematurely before all after-split folios are fully processed. This allows a concurrent operation to free the inode while subsequen...

CVE-2026-72180

CVE-2026-72180 affects the Linux kernel’s huge memory handling (mm/huge_memory). The root cause is that during device-private PMD downgrade, the pmd_swp_uffd_wp flag can be lost when the swap entry is rewritten, allowing a plain mprotect() on a UFFD_WP-marked device-private THP to strip the flag ...

CVE-2026-68163

The CVE-2026-68163 entry concerns Linux kernel memory management: device-private PMD handling in page_vma_mapped_walk() and related code paths. Root cause was improper handling of device-private PMD entries after adding device-private support, leading to cases where PMD entries with PFNs could be...
