Description

CVE-2025-71118 affecting package kernel for versions less than 6.6.121.1-1

In the Linux kernel, the following vulnerability has been resolved:

ACPICA: Avoid walking the Namespace if start_node is NULL

Although commit 0c9992315e73 ("ACPICA: Avoid walking the ACPI Namespace

if it is not there") fixed the situation when both start_node and

acpi_gbl_root_node are NULL, the Linux kernel mainline now still crashed

on Honor Magicbook 14 Pro [1].

That happens due to the access to the member of parent_node in

acpi_ns_get_next_node(). The NULL pointer dereference will always

happen, no matter whether or not the start_node is equal to

ACPI_ROOT_OBJECT, so move the check of start_node being NULL

out of the if block.

Unfortunately, all the attempts to contact Honor have failed, they

refused to provide any technical support for Linux.

The bad DSDT table's dump could be found on GitHub [2].

DMI: HONOR FMB-P/FMB-P-PCB, BIOS 1.13 05/08/2025
