In the Linux kernel, the following vulnerability has been resolved:

mm/page_alloc: change all pageblocks migrate type on coalescing

When a page is freed it coalesces with a buddy into a higher order page while possible. When the buddy page migrate type differs, it is expected to be updated to match the one of the page being freed.

However, only the first pageblock of the buddy page is updated, while the rest of the pageblocks are left unchanged.

That causes warnings in later expand() and other code paths (like below), since an inconsistency between migration type of the list containing the page and the page-owned pageblocks migration types is introduced.

OESA-2026-1760 — kernel security update

2026-10-05T18:14:23.384645+00:00

Affected: openEuler:24.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

iommu/s390: Implement blocking domain

This fixes a crash when surprise hot-unplugging a PCI device. This crash happens because during hot-unplug __iommu_group_set_domain_nofail() attaching the default domain fails when the platform no longer recognizes the device as it has already been removed and we end up with a NULL domain pointer and UAF. This is exactly the case referred to in the second comment in __iommu_device_set_domain() and just as stated there if we can instead attach the blocking domain the UAF is prevented as this can handle the already removed device. Implement the blocking domain to use this handling. With this change, the crash is fixed but we still hit a warning attempting to change DMA ownership on a blocked device.(CVE-2024-53232)

In the Linux kernel, the following vulnerability has been resolved:

iommu: Fix two issues in iommu_copy_struct_from_user()

In the review for iommu_copy_struct_to_user() helper, Matt pointed out that a NULL pointer should be rejected prior to dereferencing it: https://lore.kernel.org/all/(CVE-2025-37900)

In the Linux kernel, the following vulnerability has been resolved:
