Background
The phy: qcom-qmp package is a component of the Linux Kernel ecosystem. It provides support for Qualcomm Quick Charge 3.0 and 4.0 technologies, which enable fast charging capabilities on Qualcomm Snapdragon devices. The package includes the necessary drivers and functionality to manage the charging process. However, a vulnerability has been identified in the package that can lead to a struct clk leak on probe errors.
Vulnerability Detail
The vulnerability in phy: qcom-qmp arises from a struct clk leak that occurs when probe errors are encountered. During the initialization process, if an error occurs in the probe function, the package fails to properly release the allocated struct clk resources. This can result in a resource leak, leading to potential memory corruption or system instability. An attacker with local access to the affected system could potentially exploit this vulnerability to execute arbitrary code or cause a denial-of-service (DoS) condition.
