Echo: linux: security update to 6.12.85-1

high Tenable Cloud Security Plugin ID 459521

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: net: usb: cdc_ncm: add ndpoffset to
 NDP32 nframes bounds check The same bounds-check bug fixed for NDP16 in the previous patch also exists in
 cdc_ncm_rx_verify_ndp32(). The DPE array size is validated against the total skb length without accounting
 for ndpoffset, allowing out-of-bounds reads when the NDP32 is placed near the end of the NTB. Add
 ndpoffset to the nframes bounds check and use struct_size_t() to express the NDP-plus-DPE-array size more
 clearly. Compile-tested only. (CVE-2026-23447)

Solution

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