  "summary": "iommu/msm: Unwind probe state on registration failure",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\niommu/msm: Unwind probe state on registration failure\n\nmsm_iommu_probe() adds its devm-managed IOMMU object to\nqcom_iommu_devices before adding the IOMMU sysfs device and registering\nit with the IOMMU core.\n\nIf iommu_device_sysfs_add() fails, probe returns with the object still on\nqcom_iommu_devices. The driver core then releases the devm allocation,\nleaving a dangling list entry that later list walks may dereference.\n\nIf iommu_device_register() fails, the same dangling list entry remains\nand the sysfs device is left registered as well.\n\nUnwind the sysfs device and global list entry in reverse setup order on\nthe corresponding failure paths.",
