  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\niommu/vt-d: Fix RB-tree corruption in probe error path\n\nThe info-\u003enode RB-tree member is zero-initialized via kzalloc. If\na device does not support ATS, the device_rbtree_insert() call is\nskipped. If a subsequent probe step fails, the error path jumps to\ndevice_rbtree_remove(), which misinterprets the zeroed node as\na tree root and corrupts the device RB-tree.\n\nFix this by explicitly initializing the RB-node as empty using\nRB_CLEAR_NODE() during initialization and guarding the removal with\nRB_EMPTY_NODE().",
