Echo: linux: security update to 6.1.170-1

high Tenable Cloud Security Plugin ID 460155

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: nvdimm/bus: Fix potential use after
 free in asynchronous initialization Dingisoul with KASAN reports a use after free if device_add() fails in
 nd_async_device_register(). Commit b6eae0f61db2 ("libnvdimm: Hold reference on parent while scheduling
 async init") correctly added a reference on the parent device to be held until asynchronous initialization
 was complete. However, if device_add() results in an allocation failure the ref count of the device drops
 to 0 prior to the parent pointer being accessed. Thus resulting in use after free. The bug bot AI
 correctly identified the fix. Save a reference to the parent pointer to be used to drop the parent
 reference regardless of the outcome of device_add(). (CVE-2026-31399)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
