Echo: linux: security update to 6.1.170-1

medium Tenable Cloud Security Plugin ID 462452

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. [1]
