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.
