Echo: linux: security update to 6.1.153-1

high Tenable Self-Hosted Container Security Plugin ID 455210

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: rose: convert 'use' field to
 refcount_t The 'use' field in struct rose_neigh is used as a reference counter but lacks atomicity. This
 can lead to race conditions where a rose_neigh structure is freed while still being referenced by other
 code paths. For example, when rose_neigh->use becomes zero during an ioctl operation via rose_rt_ioctl(),
 the structure may be removed while its timer is still active, potentially causing use-after-free issues.
 This patch changes the type of 'use' from unsigned short to refcount_t and updates all code paths to use
 rose_neigh_hold() and rose_neigh_put() which operate reference counts atomically. (CVE-2025-39826)

Solution

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