Echo: linux: security update to 6.1.162-1

medium Tenable Cloud Security Plugin ID 465161

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: uacce: implement mremap in
uacce_vm_ops to return -EPERM The current uacce_vm_ops does not support the mremap operation of
vm_operations_struct. Implement .mremap to return -EPERM to remind users. The reason we need to explicitly
disable mremap is that when the driver does not implement .mremap, it uses the default mremap method. This
could lead to a risk scenario: An application might first mmap address p1, then mremap to p2, followed by
munmap(p1), and finally munmap(p2). Since the default mremap copies the original vma's vm_private_data
(i.e., q) to the new vma, both munmap operations would trigger vma_close, causing q->qfr to be freed
twice(qfr will be set to null here, so repeated release is ok). (CVE-2026-23056)

Solution

Update the linux library and its related packages to version 6.1.162-1 or later.
