Echo: linux: security update to 6.1.153-1

high Tenable Cloud Security Plugin ID 462624

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: fix OOB read/write in
 network-coding decode batadv_nc_skb_decode_packet() trusts coded_len and checks only against skb->len. XOR
 starts at sizeof(struct batadv_unicast_packet), reducing payload headroom, and the source skb length is
 not verified, allowing an out-of-bounds read and a small out-of-bounds write. Validate that coded_len fits
 within the payload area of both destination and source sk_buffs before XORing. (CVE-2025-39839)

Solution

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