In the Linux kernel, the following vulnerability has been resolved:
net: qrtr: replace qrtr_tx_flow radix_tree with xarray to fix memory leak
__radix_tree_create() allocates and links intermediate nodes into the
tree one by one. If a subsequent allocation fails, the already-linked
nodes remain in the tree with no corresponding leaf entry. These orphaned
internal nodes are never reclaimed because radix_tree_for_each_slot()
only visits slots containing leaf values.
The radix_tree API is deprecated in favor of xarray. As suggested by
Matthew Wilcox, migrate qrtr_tx_flow from radix_tree to xarray instead
of fixing the radix_tree itself [1]. xarray properly handles cleanup of
internal nodes — xa_destroy() frees all internal xarray nodes when the
qrtr_node is released, preventing the leak.
