Echo: linux: security update to 6.12.17-1

medium Tenable Self-Hosted Container Security Plugin ID 465555

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: ASoC: SOF: ipc4-topology: Harden loops
 for looking up ALH copiers Other, non DAI copier widgets could have the same stream name (sname) as the
 ALH copier and in that case the copier->data is NULL, no alh_data is attached, which could lead to NULL
 pointer dereference. We could check for this NULL pointer in sof_ipc4_prepare_copier_module() and avoid
 the crash, but a similar loop in sof_ipc4_widget_setup_comp_dai() will miscalculate the ALH device count,
 causing broken audio. The correct fix is to harden the matching logic by making sure that the 1. widget is
 a DAI widget - so dai = w->private is valid 2. the dai (and thus the copier) is ALH copier
 (CVE-2025-21870)

Solution

Update the linux library and its related packages to version 6.12.17-1 or later.
