Echo: linux: security update to 6.1.147-1

high Tenable Self-Hosted Container Security Plugin ID 459969

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: rose: fix dangling neighbour pointers
in rose_rt_device_down() There are two bugs in rose_rt_device_down() that can cause use-after-free: 1. The
loop bound `t->count` is modified within the loop, which can cause the loop to terminate early and miss
some entries. 2. When removing an entry from the neighbour array, the subsequent entries are moved up to
fill the gap, but the loop index `i` is still incremented, causing the next entry to be skipped. For
example, if a node has three neighbours (A, A, B) with count=3 and A is being removed, the second A is not
checked. i=0: (A, A, B) -> (A, B) with count=2 ^ checked i=1: (A, B) -> (A, B) with count=2 ^ checked (B,
not A!) i=2: (doesn't occur because i < count is false) This leaves the second A in the array with
count=2, but the rose_neigh structure has been freed. Code that accesses these entries assumes that the
first `count` entries are valid pointers, causing a use-after-free when it accesses the dangling pointer.
Fix both issues by iterating over the array in reverse order with a fixed loop bound. This ensures that
all entries are examined and that the removal of an entry doesn't affect subsequent iterations.
(CVE-2025-38377)
