clocksource\/drivers\/nxp-pit: Fix IRQ leak on cpuhp_setup_state error path<\/p>\n
When cpuhp_setup_state fails after pit_clockevent_per_cpu_init has
\nsuccessfully called request_irq, the error handling jumps directly to
\nout_pit_clocksource_unregister without freeing the registered IRQ.<\/p>\n
This leaks the IRQ line and, since kfree(pit) follows, leaves a
\ndangling pointer registered as the interrupt handler’s dev_id,
\npotentially leading to a use-after-free if the IRQ fires afterwards.<\/p>\n
Fix it by calling pit_clockevent_per_cpu_exit to properly release the
\nIRQ before falling through to the existing cleanup chain.<\/p>\n","protected":false},"excerpt":{"rendered":"
