Description
In the Linux kernel, the following vulnerability has been resolved: remoteproc: sysmon: fix memory leak in qcom_add_sysmon_subdev() The kfree() should be called when of_irq_get_byname() fails or devm_request_threaded_irq() fails in qcom_add_sysmon_subdev(), otherwise there will be a memory leak, so add kfree() to fix it.

Executive Summary

This vulnerability is a memory leak in the Linux kernel's remoteproc subsystem, specifically in the sysmon component's function qcom_add_sysmon_subdev(). When certain functions (of_irq_get_byname() or devm_request_threaded_irq()) fail, the code does not properly free allocated memory, leading to a memory leak. The fix involves adding a kfree() call to release the memory in these failure cases.

Impact Analysis

The memory leak caused by this vulnerability can lead to increased memory usage over time, potentially degrading system performance or causing resource exhaustion on affected Linux systems using the remoteproc sysmon component.

Mitigation Strategies

Apply the updated Linux kernel patch that fixes the memory leak in the qcom_add_sysmon_subdev() function by ensuring kfree() is called appropriately when of_irq_get_byname() or devm_request_threaded_irq() fails.
