"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/x86/amd/pmc: Only disable IRQ1 wakeup where i8042 actually enabled it\n\nWakeup for IRQ1 should be disabled only in cases where i8042 had\nactually enabled it, otherwise \"wake_depth\" for this IRQ will try to\ndrop below zero and there will be an unpleasant WARN() logged:\n\nkernel: atkbd serio0: Disabling IRQ1 wakeup source to avoid platform firmware bug\nkernel: ------------[ cut here ]------------\nkernel: Unbalanced IRQ 1 wake disable\nkernel: WARNING: CPU: 10 PID: 6431 at kernel/irq/manage.c:920 irq_set_irq_wake+0x147/0x1a0\n\nThe PMC driver uses DEFINE_SIMPLE_DEV_PM_OPS() to define its dev_pm_ops\nwhich sets amd_pmc_suspend_handler() to the .suspend, .freeze, and\n.poweroff handlers. i8042_pm_suspend(), however, is only set as\nthe .suspend handler.\n\nFix the issue by call PMC suspend handler only from the same set of\ndev_pm_ops handlers as i8042_pm_suspend(), which currently means just\nthe .suspend handler.\n\nTo reproduce this issue try hibernating (S4) the machine after a fresh boot\nwithout putting it into s2idle first.\n\n[ij: edited the commit message.]"
