      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: qrtr: replace qrtr_tx_flow radix_tree with xarray to fix memory leak\n\n__radix_tree_create() allocates and links intermediate nodes into the\ntree one by one. If a subsequent allocation fails, the already-linked\nnodes remain in the tree with no corresponding leaf entry. These orphaned\ninternal nodes are never reclaimed because radix_tree_for_each_slot()\nonly visits slots containing leaf values.\n\nThe radix_tree API is deprecated in favor of xarray. As suggested by\nMatthew Wilcox, migrate qrtr_tx_flow from radix_tree to xarray instead\nof fixing the radix_tree itself [1]. xarray properly handles cleanup of\ninternal nodes — xa_destroy() frees all internal xarray nodes when the\nqrtr_node is released, preventing the leak.\n\n[1] https://lore.kernel.org/all/20260225071623.41275-1-jiayuan.chen@linux.dev/T/",
