Echo: linux: security update to 6.12.96-1

high Tenable Self-Hosted Container Security Plugin ID 462804

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: free iso schedules on failed
 submit EHCI and FOTG210 isochronous submits build an ehci_iso_sched before linking the URB to the endpoint
 queue, and keep the staged schedule in urb->hcpriv until iso_stream_schedule() and the link helpers
 consume it. If the controller is no longer accessible, or usb_hcd_link_urb_to_ep() fails, submit jumps to
 done_not_linked before that handoff happens and leaks the staged schedule still attached to urb->hcpriv.
 Free the staged schedule from done_not_linked when submit fails before the URB is linked and clear
 urb->hcpriv after the free. The bug was first flagged by an experimental analysis tool we are developing
 for kernel memory-management bugs while analyzing v6.13-rc1. The tool is still under development and is
 not yet publicly available. Manual inspection confirms that the bug is still present in v7.1.1. An x86_64
 allyesconfig build showed no new warnings. As we do not have an EHCI host controller with a USB
 isochronous device to test with, no runtime testing was able to be performed. (CVE-2026-64348)

Solution

Update the linux library and its related packages to version 6.12.96-1 or later.
