Background

The ACPI (Advanced Configuration and Power Interface) is an open standard for power management and configuration of computer hardware. It provides a platform-independent interface for controlling power and configuration settings. The ACPI scan function is responsible for detecting and initializing ACPI devices in the system. However, a memory leak vulnerability has been identified in the error handling path of the ACPI scan function.

Vulnerability Detail

The vulnerability in the ACPI scan function can lead to a memory leak. When an error occurs during the scanning process, memory allocated for ACPI devices may not be properly freed, resulting in a memory leak. An attacker could potentially exploit this vulnerability to exhaust system memory resources, leading to a denial-of-service condition. The impact and attack plausibility of this vulnerability have not been proven yet.

FAQ

ACPI (Advanced Configuration and Power Interface) is an open standard for power management and configuration of computer hardware.

The ACPI scan function is responsible for detecting and initializing ACPI devices in the system.

A memory leak is a type of software defect where memory that is no longer needed is not properly released, leading to a gradual loss of available memory resources.

The impact of this vulnerability is a potential denial-of-service condition due to the exhaustion of system memory resources.

To fix this vulnerability, it is recommended to update the Linux Kernel to version v5.12.5 or later.
