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.

A flaw was found in the Linux kernel's ipu6 driver. This issue occurs due to a runtime Power Management (PM) reference leak in the driver's probe error paths. When errors occur during device initialization, PM references are not properly released, which can lead to resource exhaustion and potentially result in a denial of service.
