Overview

CVE-2022-50411 is a high-severity vulnerability. It was published on September 18, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

ACPICA: Fix error code path in acpi_ds_call_control_method()

A use-after-free in acpi_ps_parse_aml() after a failing invocaion of

acpi_ds_call_control_method() is reported by KASAN [1] and code

inspection reveals that next_walk_state pushed to the thread by

acpi_ds_create_walk_state() is freed on errors, but it is not popped

from the thread beforehand. Thus acpi_ds_get_current_walk_state()

called by acpi_ps_parse_aml() subsequently returns it as the new

walk state which is incorrect.

To address this, make acpi_ds_call_control_method() call

acpi_ds_pop_walk_state() to pop next_walk_state from the thread before

returning an error.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
