Background
The phy: qcom-qmp package is a component of the Linux Kernel ecosystem. It provides support for the Qualcomm QMP (Qualcomm Message Passing) PHY (Physical Layer) controller. This controller is responsible for managing the physical layer of communication between devices. The package is widely used in various Linux-based systems and devices. However, a vulnerability has been discovered in the package that can lead to a reset-controller leak on probe errors.
Vulnerability Detail
The vulnerability in the phy: qcom-qmp package occurs when there are probe errors during initialization. In such cases, the reset-controller is not properly released, leading to a resource leak. This vulnerability can potentially be exploited by an attacker to exhaust system resources and cause a denial-of-service condition. The vulnerability was introduced in version v4.12 of the Linux Kernel and has been fixed in version v4.14.283 by commit b7b5fbcaac5355e2e695dc0c08a0fcf248250388.
