Echo: linux: security update to 6.12.85-1

high Tenable Cloud Security Plugin ID 463207

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: usb: typec: ucsi: validate connector
 number in ucsi_notify_common() The connector number extracted from CCI via UCSI_CCI_CONNECTOR() is a 7-bit
 field (0-127) that is used to index into the connector array in ucsi_connector_change(). However, the
 array is only allocated for the number of connectors reported by the device (typically 2-4 entries). A
 malicious or malfunctioning device could report an out-of-range connector number in the CCI, causing an
 out-of-bounds array access in ucsi_connector_change(). Add a bounds check in ucsi_notify_common(), the
 central point where CCI is parsed after arriving from hardware, so that bogus connector numbers are
 rejected before they propagate further. (CVE-2026-31729)

Solution

Update the linux library and its related packages to version 6.12.85-1 or later.
