GHSA-36J9-2V33-G5MG
Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2025-11-04 18:31In 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.
