The loop decrements the index but fails to update the vr pointer, which still points to the VR that caused the failure. As a result, the condition and the rollback call always operate on the same VR, potentially calling mlxsw_sp_vr_lpm_tree_replace() multiple times on it while never rolling back the earlier VRs. Those VRs continue to hold a reference to new_tree acquired via mlxsw_sp_lpm_tree_hold(), leaking the reference count of new_tree.</p> <p>Fix by reinitializing vr inside the error loop with the updated index:</p> <p>vr = &amp;mlxsw_sp-&gt;router-&gt;vrs[i];</p> <p>so that the loop correctly iterates over all VRs that were actually replaced.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>mlxsw: fix refcount leak in mlxsw_sp_vrs_lpm_tree_replace()</p> <p>When mlxsw_sp_vrs_lpm_tree_replace() fails after replacing some VRs, the error rollback loop does not correctly revert the preceding replacements.
