Background
The i2c package is a component of the Linux Kernel ecosystem. It provides support for the Inter-Integrated Circuit (I2C) bus protocol, allowing communication between integrated circuits on a computer motherboard. The ACPI (Advanced Configuration and Power Interface) subsystem in the Linux Kernel is responsible for managing hardware resources and power management. This vulnerability specifically affects the ACPI driver for i2c, which is used for reconfiguration device addition.
Vulnerability Detail
The vulnerability in the i2c: acpi package involves a resource leak in the reconfiguration device addition process. When adding a reconfiguration device, resources are not properly released, leading to a potential resource exhaustion issue. An attacker could exploit this vulnerability to exhaust system resources, potentially causing a denial-of-service (DoS) condition. The impact and attack plausibility of this vulnerability have not been proven yet.
