If a device does not support ATS, the device_rbtree_insert() call is skipped. If a subsequent probe step fails, the error path jumps to device_rbtree_remove(), which misinterprets the zeroed node as a tree root and corrupts the device RB-tree.</p> <p>Fix this by explicitly initializing the RB-node as empty using RB_CLEAR_NODE() during initialization and guarding the removal with RB_EMPTY_NODE().</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>iommu/vt-d: Fix RB-tree corruption in probe error path</p> <p>The info-&gt;node RB-tree member is zero-initialized via kzalloc.
