Linux Kernel IPC Runtime State Vulnerability in IVPU Acceleration Component

A vulnerability in the Linux kernel's IVPU acceleration component has been addressed. The issue was related to the improper management of the runtime power state in the IPC (Inter-Process Communication) send-receive function. The vulnerability arose because the IPC function could be executed before the power management was correctly initialized, leading to potential warnings or errors. The fix involved moving the power management initialization to ensure the IPC function operates with the correct runtime state, even if the last resume operation was unsuccessful.

Impact

The vulnerability could lead to improper power management, causing runtime state errors in the IPC communication process, which may disrupt normal operations or performance.
