Echo: linux: security update to 6.1.170-1

medium Tenable Cloud Security Plugin ID 464193

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: can: ucan: Fix infinite loop from
 zero-length messages If a broken ucan device gets a message with the message length field set to 0, then
 the driver will loop for forever in ucan_read_bulk_callback(), hanging the system. If the length is 0,
 just skip the message and go on to the next one. This has been fixed in the kvaser_usb driver in the past
 in commit 0c73772cd2b8 ("can: kvaser_usb: leaf: Fix potential infinite loop in command parsers"), so there
 must be some broken devices out there like this somewhere. (CVE-2026-23298)

Solution

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