In the Linux kernel, the following vulnerability has been resolved:
iommu/msm: Unwind probe state on registration failure
msm_iommu_probe() adds its devm-managed IOMMU object to
qcom_iommu_devices before adding the IOMMU sysfs device and registering
it with the IOMMU core.
If iommu_device_sysfs_add() fails, probe returns with the object still on
qcom_iommu_devices. The driver core then releases the devm allocation,
leaving a dangling list entry that later list walks may dereference.
If iommu_device_register() fails, the same dangling list entry remains
and the sysfs device is left registered as well.
Unwind the sysfs device and global list entry in reverse setup order on
the corresponding failure paths.
