Background
The soc: qcom: rpmpd package is a component of the Linux Kernel. It is responsible for managing the Qualcomm RPM power domain. The RPM power domain is a power management subsystem that controls the power supply to various components of a Qualcomm SoC. The soc: qcom: rpmpd package provides the necessary functionality to interact with and control the RPM power domain. However, a vulnerability has been discovered in this package that could potentially lead to security issues.
Vulnerability Detail
The vulnerability in soc: qcom: rpmpd is related to a null return check in the devm_kcalloc function. This function is used to allocate memory for an array of objects with the specified size. However, the code does not check for a null return value after calling devm_kcalloc, which could lead to a null pointer dereference and subsequent crashes or other security issues. An attacker could potentially exploit this vulnerability to execute arbitrary code or cause a denial of service. The vulnerability was introduced in version v5.1 of the Linux Kernel and has been fixed in version v5.16.19.
