# \[PATCH\] powerpc/powernv: Free name on error in opal\_event\_init() - From: Michael Ellerman \ - Date: 2024-09-20 09:35:28 - List: linuxppc-dev - Page: https://ratatoskr.run/linuxppc-dev/2024/09/9534601 - Thread: https://ratatoskr.run/linuxppc-dev/2024/09/9534601/t.md ```text In opal_event_init() if request_irq() fails name is not freed, leading to a memory leak. The code only runs at boot time, there's no way for a user to trigger it, so there's no security impact. Fix the leak by freeing name in the error path.
