Echo: linux: security update to 6.1.170-1

medium Tenable Self-Hosted Container Security Plugin ID 464349

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: comedi: ni_atmio16d: Fix invalid
clean-up after failed attach If the driver's COMEDI "attach" handler function (`atmio16d_attach()`)
returns an error, the COMEDI core will call the driver's "detach" handler function (`atmio16d_detach()`)
to clean up. This calls `reset_atmio16d()` unconditionally, but depending on where the error occurred in
the attach handler, the device may not have been sufficiently initialized to call `reset_atmio16d()`. It
uses `dev->iobase` as the I/O port base address and `dev->private` as the pointer to the COMEDI device's
private data structure. `dev->iobase` may still be set to its initial value of 0, which would result in
undesired writes to low I/O port addresses. `dev->private` may still be `NULL`, which would result in null
pointer dereferences. Fix `atmio16d_detach()` by checking that `dev->private` is valid (non-null) before
calling `reset_atmio16d()`. This implies that `dev->iobase` was set correctly since that is set up before
`dev->private`. (CVE-2026-31749)

Solution

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