Echo: linux: security update to 6.1.176-1

high Tenable Cloud Security Plugin ID 458188

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: tap: free page on error paths in
 tap_get_user_xdp() tap_get_user_xdp() rejects a frame shorter than ETH_HLEN with -EINVAL, and returns
 -ENOMEM when build_skb() fails. Both paths jump to the err label without freeing the page that
 vhost_net_build_xdp() allocated for the frame. tap_sendmsg() discards the per-buffer return value and
 always returns 0, so vhost_tx_batch() takes the success path and never frees the page; each rejected frame
 in a batch leaks one page-frag chunk. Free the page on both error paths, before the skb is built. This is
 the tap counterpart of the same leak in tun_xdp_one(). (CVE-2026-46320)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
