Echo: linux: security update to 6.1.135-1

medium Tenable Cloud Security Plugin ID 457490

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: usbnet:fix NPE during rx_complete
 Missing usbnet_going_away Check in Critical Path. The usb_submit_urb function lacks a usbnet_going_away
 validation, whereas __usbnet_queue_skb includes this check. This inconsistency creates a race condition
 where: A URB request may succeed, but the corresponding SKB data fails to be queued. Subsequent processes:
 (e.g., rx_complete → defer_bh → __skb_unlink(skb, list)) attempt to access skb->next, triggering a NULL
 pointer dereference (Kernel Panic). (CVE-2025-22050)

Solution

Update the linux library and its related packages to version 6.1.135-1 or later.
