Background

The phy: qcom-qmp package is a component of the Linux Kernel ecosystem. It provides support for Qualcomm QMP (Qualcomm Message Passing) PHYs. These PHYs are responsible for managing communication between different hardware components in Qualcomm SoCs (System-on-Chips). The qcom-qmp package is utilized by various devices that rely on Qualcomm SoCs for their functionality.

Vulnerability Detail

The vulnerability in the phy: qcom-qmp package involves a reset-controller leak that occurs on probe errors. When the package encounters an error during the initialization process (probe), it fails to release the reset-controller, leading to a resource leak. This vulnerability can potentially result in resource exhaustion and system instability. It was introduced in version v4.12 of the Linux Kernel and has been fixed in version v5.18.3.

How To Fix

No fixed version is published for this vulnerability.

To fix this vulnerability, it is recommended to update the Linux Kernel to version v5.18.3 or later. This update includes the commit 8c03eb0c8982677b4e17174073a011788891304d, which resolves the reset-controller leak issue. Users can obtain the updated kernel from the official Linux Kernel repository: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/
