Echo: linux: security update to 6.1.176-1

high Tenable Cloud Security Plugin ID 461183

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: batman-adv: dat: handle forward
 allocation error batadv_dat_forward_data() calls pskb_copy_for_clone() to duplicate an skb for each DHT
 candidate, but does not check the return value before passing it to
 batadv_send_skb_prepare_unicast_4addr(). That function dereferences the skb unconditionally, so a failed
 allocation triggers a NULL pointer dereference. Skip forwarding to the current DHT candidate on allocation
 failure. (CVE-2026-52922)

Solution

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