Echo: linux: security update to 6.1.170-1

medium Tenable Self-Hosted Container Security Plugin ID 459496

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: Bluetooth: btusb: clamp SCO altsetting
table indices btusb_work() maps the number of active SCO links to USB alternate settings through a three-
entry lookup table when CVSD traffic uses transparent voice settings. The lookup currently indexes alts[]
with data->sco_num - 1 without first constraining sco_num to the number of available table entries. While
the table only defines alternate settings for up to three SCO links, data->sco_num comes from
hci_conn_num() and is used directly. Cap the lookup to the last table entry before indexing it so the
driver keeps selecting the highest supported alternate setting without reading past alts[].
(CVE-2026-31497)

Solution

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