CVE-2025-38335

CVE-2025-38335 concerns a Linux kernel vulnerability in the gpio_keys driver related to PREEMPT_RT. The description states that when PREEMPT_RT is enabled, gpio_keys_irq_timer() can run in hard IRQ context while input_event() uses a spin_lock, which is incompatible with hard IRQ. This leads to a ...
