"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nPM: core: keep irq flags in device_pm_check_callbacks()\n\nThe function device_pm_check_callbacks() can be called under the spin\nlock (in the reported case it happens from genpd_add_device() ->\ndev_pm_domain_set(), when the genpd uses spinlocks rather than mutexes.\n\nHowever this function uncoditionally uses spin_lock_irq() /\nspin_unlock_irq(), thus not preserving the CPU flags.
