Echo: linux: security update to 6.1.170-1

medium Tenable Cloud Security Plugin ID 458199

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: cdns3: gadget: fix state
 inconsistency on gadget init failure When cdns3_gadget_start() fails, the DRD hardware is left in gadget
 mode while software state remains INACTIVE, creating hardware/software state inconsistency. When switching
 to host mode via sysfs: echo host > /sys/class/usb_role/13180000.usb-role-switch/role The role state is
 not set to CDNS_ROLE_STATE_ACTIVE due to the error, so cdns_role_stop() skips cleanup because state is
 still INACTIVE. This violates the DRD controller design specification (Figure22), which requires returning
 to idle state before switching roles. This leads to a synchronous external abort in xhci_gen_setup() when
 setting up the host controller: [ 516.440698] configfs-gadget 13180000.usb: failed to start g1: -19 [

 in the error path to properly clean up the DRD gadget state. (CVE-2026-31754)
