Description
In the Linux kernel, the following vulnerability has been resolved: media: ipu6: Fix RPM reference leak in probe error paths Several error paths in ipu6_pci_probe() were jumping directly to out_ipu6_bus_del_devices without releasing the runtime PM reference. Add pm_runtime_put_sync() before cleaning up other resources.

Executive Summary

This vulnerability is related to the Linux kernel's media subsystem, specifically the ipu6 driver. It involves a reference leak of the runtime power management (PM) in error paths of the ipu6_pci_probe() function. Some error handling paths were skipping the proper release of the runtime PM reference, which could lead to resource management issues. The fix involved adding a call to pm_runtime_put_sync() before cleaning up other resources to ensure the runtime PM reference is correctly released.

Impact Analysis

The impact of this vulnerability is primarily related to resource management within the Linux kernel's media driver. If the runtime PM reference is not properly released, it could lead to resource leaks, potentially causing increased power consumption or instability in the affected system components. However, no specific CVSS score or detailed impact information is provided.
