Detail

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: platform pxa2xx-spi.3: Adding to iommu group 20
kernel: input: Apple SPI Keyboard as

Fix this by restoring the previous context setup order.
