- Summary
- iommu/arm-smmu: fix possible null-ptr-deref in arm_smmu_device_probe()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
iommu/arm-smmu: fix possible null-ptr-deref in armsmmudevice_probe()
It will cause null-ptr-deref when using 'res', if platformgetresource() returns NULL, so move using 'res' after devmioremapresource() that will check it to avoid null-ptr-deref. And use devmplatformgetandioremap_resource() to simplify code.
