[PATCH OLK-6.6] mm/numa_remote: limit remote NUMA linear mapping to PMD granularity
by Jinjiang Tu 09 Jul '26

09 Jul '26

hulk inclusion category: bugfix bugzilla: https://atomgit.com/openeuler/kernel/issues/9543 ---------------------------------------- When hot-adding 1G memory and then hot-removing a 128MB portion, the entire 1G PUD-level page table gets torn down because the linear mapping was created at PUD block granularity. This causes valid remaining memory to lose its mapping. Fix this by forcing PMD-level block mappings for remote NUMA nodes during arch_add_memory(), so that hot-remove only tears down PMD-sized segments rather than the full PUD range. Since hot-add/hot-remove granularity is larger than PMD size, there is no risk of incorrectly removing linear mappings belonging to adjacent memory regions.

[PATCH OLK-6.6] KVM: x86: Fix shadow paging use-after-free due to unexpected role

From: Paolo Bonzini <pbonzini(a)redhat.com> stable inclusion from stable-v6.6.144 commit 9291654d69e08542de37755cebe4d5b02c3170d1 category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/16072 CVE: CVE-2026-53359 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 81ccda30b4e83d8f5cc4fd50503c44e3a33abfeb upstream. Commit 0cb2af2ea66ad ("KVM: x86: Fix shadow paging use-after-free due to unexpected GFN") fixed a shadow paging mismatch between stored and computed GFNs; the bug could be triggered by changing a PDE mapping from outside the guest, and then deleting a memslot. The rmap_remove() call would miss entries created after the PDE change because the GFN of the leaf SPTE does not match the GFN of the struct kvm_mmu_page. A similar hole however remains if the modified PDE points to a non-leaf page. In this case the gfn can be made to match, but the role does not match: the original large 2MB page creates a kvm_mmu_page with direct=1, while the new 4KB needs a kvm_mmu_page with direct=0. However, kvm_mmu_get_child_sp() does not compare the role, and therefore reuses the page. The next step is installing a leaf (4KB) SPTE on the new path which records an rmap entry under the gfn resolved by the walk. But when that child is zapped its parent kvm_mmu_page has direct=1 and kvm_mmu_page_get_gfn() computes the gfn for the 4KB page as sp->gfn + index instead of using sp->shadowed_translation[] (or sp->gfns[] in older kernels). It therefore fails to remove the recorded entry. When the memslot is dropped the shadow page is freed but the rmap entry survives, as in the scenario that was already fixed. Code that later walks that gfn (dirty logging, MMU notifier invalidation, and so on) dereferences an sptep that lies in the freed page, causing the use-after-free.
