Jul 30 RESCORED — CVE-2025-38216 (Linux). CVSS 8.8 → 7.8 (NVD).
Description
In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Restore context entry setup order for aliased devices
Commit 2031c469f816 ("iommu/vt-d: Add support for static identity domain")
changed the context entry setup during domain attachment from a
set-and-check policy to a clear-and-reset approach. This inadvertently
introduced a regression affecting PCI aliased devices behind PCIe-to-PCI
bridges.
Specifically, keyboard and touchpad stopped working on several Apple
Macbooks with below messages:

kernel: input: Apple SPI Keyboard as

Fix this by restoring the previous context setup order.
