Echo: linux: security update to 6.1.170-1

medium Tenable Self-Hosted Container Security Plugin ID 455476

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: EDAC/mc: Fix error path ordering in
edac_mc_alloc() When the mci->pvt_info allocation in edac_mc_alloc() fails, the error path will call
put_device() which will end up calling the device's release function. However, the init ordering is wrong
such that device_initialize() happens *after* the failed allocation and thus the device itself and the
release function pointer are not initialized yet when they're called: MCE: In-kernel MCE decoding enabled.
------------[ cut here ]------------ kobject: '(null)': is not initialized, yet kobject_put() is being
called. WARNING: lib/kobject.c:734 at kobject_put, CPU#22: systemd-udevd CPU: 22 UID: 0 PID: 538 Comm:
systemd-udevd Not tainted 7.0.0-rc1+ #2 PREEMPT(full) RIP: 0010:kobject_put Call Trace: <TASK>

__pfx_amd64_edac_init+0x10/0x10 [amd64_edac] do_one_initcall ... Reorder the calling sequence so that the
device is initialized and thus the release function pointer is properly set before it can be used. This
was found by Claude while reviewing another EDAC patch. (CVE-2026-31689)

Solution

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