Echo: linux: security update to 6.1.153-1

medium Tenable Cloud Security Plugin ID 462466

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: vsock/virtio: Validate length in
packet header before skb_put() When receiving a vsock packet in the guest, only the virtqueue buffer size
is validated prior to virtio_vsock_skb_rx_put(). Unfortunately, virtio_vsock_skb_rx_put() uses the length
from the packet header as the length argument to skb_put(), potentially resulting in SKB overflow if the
host has gone wonky. Validate the length as advertised by the packet header before calling
virtio_vsock_skb_rx_put(). (CVE-2025-39718)

Solution

Update the linux library and its related packages to version 6.1.153-1 or later.
