UBUNTU-CVE-2025-71118: Null Pointer Dereference

Q: Which systems are known to trigger this issue?

The crash was observed on an Honor Magicbook 14 Pro with DMI identifier HONOR FMB-P/FMB-P-PCB and BIOS 1.13 dated 05/08/2025. The issue is associated with a malformed ACPI DSDT table.

Q: What access does an attacker need to exploit this vulnerability?

The provided vector rates the issue as locally exploitable with low attack complexity and low privileges, with no user interaction required. Its documented impact is denial of service through a kernel crash; confidentiality and integrity impacts are not indicated.

Q: Are Ubuntu cloud and FIPS kernel variants listed as affected?

Yes. The listed software includes Ubuntu linux, linux-fips, linux-aws, linux-azure, linux-gcp, and their listed AWS, Azure, and GCP FIPS variants.

Q: How can I determine whether a system may be affected?

Check whether the system runs one of the listed Ubuntu kernel packages and uses firmware with a malformed ACPI DSDT table. The supplied report specifically identifies the Honor Magicbook 14 Pro firmware configuration above as reproducing the crash.

Updated

In the Linux kernel, the following vulnerability has been resolved: ACPICA: Avoid walking the Namespace if startnode is NULL Although commit 0c9992315e73 ("ACPICA: Avoid walking the ACPI Namespace if it is not there") fixed the situation when both startnode and acpigblrootnode 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 parentnode in acpinsgetnextnode(). The NULL pointer dereference will always happen, no matter whether or not the startnode is equal to ACPIROOTOBJECT, so move the check of startnode 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].
