Echo: linux: security update to 6.1.153-1

medium Tenable Cloud Security Plugin ID 465236

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: include node references in
rose_neigh refcount Current implementation maintains two separate reference counting mechanisms: the
'count' field in struct rose_neigh tracks references from rose_node structures, while the 'use' field (now
refcount_t) tracks references from rose_sock. This patch merges these two reference counting systems using
'use' field for proper reference management. Specifically, this patch adds incrementing and decrementing
of rose_neigh->use when rose_neigh->count is incremented or decremented. This patch also modifies
rose_rt_free(), rose_rt_device_down() and rose_clear_route() to properly release references to rose_neigh
objects before freeing a rose_node through rose_remove_node(). These changes ensure rose_neigh structures
are properly freed only when all references, including those from rose_node structures, are released. As a
result, this resolves a slab-use-after-free issue reported by Syzbot. (CVE-2025-39827)

Solution

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