  3. CVE-2025-38216
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 /devices/pci0000:00/0000:00:1e.3/pxa2xx-spi.3/spi_master/spi2/spi-APP000D:00/input/input0 kernel: DMAR: DRHD: handling fault status reg 3 kernel: DMAR: [DMA Read NO_PASID] Request device [00:1e.3] fault addr 0xffffa000 [fault reason 0x06] PTE Read access is not set kernel: DMAR: DRHD: handling fault status reg 3 kernel: DMAR: [DMA Read NO_PASID] Request device [00:1e.3] fault addr 0xffffa000 [fault reason 0x06] PTE Read access is not set kernel: applespi spi-APP000D:00: Error writing to device: 01 0e 00 00 kernel: DMAR: DRHD: handling fault status reg 3 kernel: DMAR: [DMA Read NO_PASID] Request device [00:1e.3] fault addr 0xffffa000 [fault reason 0x06] PTE Read access is not set kernel: DMAR: DRHD: handling fault status reg 3 kernel: applespi spi-APP000D:00: Error writing to device: 01 0e 00 00 Fix this by restoring the previous context setup order.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: iommu/vt-d: Restaurar el orden de configuración de la entrada de contexto para dispositivos con alias. El commit 2031c469f816 ("iommu/vt-d: Añadir compatibilidad con dominio de identidad estática") cambió la configuración de la entrada de contexto durante la conexión del dominio, de una política de "establecer y comprobar" a una de "borrar y restablecer". Esto introdujo inadvertidamente una regresión que afectaba a los dispositivos con alias PCI tras puentes PCIe a PCI. Específicamente, el teclado y el panel táctil dejaron de funcionar en varias Apple Macbooks con los siguientes mensajes: kernel: platform pxa2xx-spi.3: Adding to iommu group 20 kernel: input: Apple SPI Keyboard as /devices/pci0000:00/0000:00:1e.3/pxa2xx-spi.3/spi_master/spi2/spi-APP000D:00/input/input0 kernel: DMAR: DRHD: handling fault status reg 3 kernel: DMAR: [DMA Read NO_PASID] Request device [00:1e.3] fault addr 0xffffa000 [fault reason 0x06] PTE Read access is not set kernel: DMAR: DRHD: handling fault status reg 3 kernel: DMAR: [DMA Read NO_PASID] Request device [00:1e.3] fault addr 0xffffa000 [fault reason 0x06] PTE Read access is not set kernel: applespi spi-APP000D:00: Error writing to device: 01 0e 00 00 kernel: DMAR: DRHD: handling fault status reg 3 kernel: DMAR: [DMA Read NO_PASID] Request device [00:1e.3] fault addr 0xffffa000 [fault reason 0x06] PTE Read access is not set kernel: DMAR: DRHD: handling fault status reg 3 kernel: applespi spi-APP000D:00: Error writing to device: 01 0e 00 00 Solucione esto restaurando el orden de configuración del contexto anterior.
