CVE-2026-80719

CVE-2026-80719 affects the MGLRU (multi-gen LRU) memory management subsystem in the Linux kernel . A race condition exists between the mglru page table walker, which batches per-generation size deltas without holding the lruvec lock, and the memcg reparenting path. This can cause stale batch upda...

CVE-2026-72043

A flaw was found in the Linux kernel, specifically affecting the LoongArch architecture when the hardware page table walker PTW is enabled. This vulnerability stems from a missing dirty page tracking mechanism in the ptewrprotect and pmdwrprotect functions, which can lead to incorrect handling of...

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Fix missing dirty page tracking in pte,pmdwrprotect When hardware page table walker PTW is enabled on LoongArch, the CPU may set PAGEDIRTY directly in the page table entry during a write TLB miss, without going through...

CVE-2024-45024

In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: fix hugetlb vs. core-mm PT locking We recently made GUP's common page table walking code to also walk hugetlb VMAs without most hugetlb special-casing, preparing for the future of having less hugetlb-specific page tab...

CVE-2024-45024

CVE-2024-45024 relates to a Linux kernel Hugetlb PT locking issue fixed by aligning huge page table locking with core-mm PT walkers. The root cause: during GUP’s shared page-table walking, hugetlb folios spanning multiple PTEs could be locked using PTE table locks (pte_offset_map_lock) while core...
