CVE-2025-37748

In the Linux kernel, the following vulnerability has been resolved: iommu/mediatek: Fix NULL pointer deference in mtk_iommu_device_group Currently, mtk_iommu calls during probe iommu_device_register before the hw_list from driver data is initialized. Since iommu probing issue fix, it leads to NULL pointer dereference in mtk_iommu_device_group when hw_list is accessed with list_first_entry (not null safe). So, change the call order to ensure iommu_device_register is called after the driver data are initialized.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: iommu/mediatek: Se ha corregido la deferencia de puntero nulo en mtk_iommu_device_group. Actualmente, mtk_iommu invoca durante el sondeo de iommu_device_register antes de que se inicialice hw_list de los datos del controlador. Desde la corrección del problema de sondeo de iommu, este provoca la desreferencia de puntero nulo en mtk_iommu_device_group cuando se accede a hw_list con list_first_entry (no es seguro para nulos). Por lo tanto, se debe modificar el orden de las llamadas para garantizar que iommu_device_register se invoque después de inicializar los datos del controlador.
