Echo: linux: security update to 6.1.176-1

medium Tenable Cloud Security Plugin ID 463995

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: pmdomain: core: Fix detach procedure
for virtual devices in genpd If a device is attached to a PM domain through genpd_dev_pm_attach_by_id(),
genpd calls pm_runtime_enable() for the corresponding virtual device that it registers. While this avoids
boilerplate code in drivers, there is no corresponding call to pm_runtime_disable() in
genpd_dev_pm_detach(). This means these virtual devices are typically detached from its genpd, while
runtime PM remains enabled for them, which is not how things are designed to work. In worst cases it may
lead to critical errors, like a NULL pointer dereference bug in genpd_runtime_suspend(), which was
recently reported. For another case, we may end up keeping an unnecessary vote for a performance state for
the device. To fix these problems, let's add this missing call to pm_runtime_disable() in
genpd_dev_pm_detach(). (CVE-2026-46292)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
