NVD description

In the Linux kernel, the following vulnerability has been resolved: clocksource/drivers/samsung_pwm: Switch to raw_spinlock_t type Samsung PWM timer might be used as a clock source on some legacy systems. When PREEMPT_RT is enabled on ARM, regular spinlock is converted to a sleeping lock (mutex-based), which must not be used in atomic context such as hard interrupt handlers. Switch the samsung_pwm_lock to the raw_spinlock, which remains a true non-sleeping spinlock even under PREEMPT_RT.
