CVE-2025-38386 Information

Description

In the Linux kernel the following vulnerability has been resolved:

ACPICA: Refuse to evaluate a method if arguments are missing

As reported in [1] a platform firmware update that increased the number of method parameters and forgot to update a least one of its callers caused ACPICA to crash due to use-after-free.

Since this a result of a clear AML issue that arguably cannot be fixed up by the interpreter (it cannot produce missing data out of thin air) address it by making ACPICA refuse to evaluate a method if the caller attempts to pass fewer arguments than expected to it.
