UBUNTU-CVE-2025-38335

In the Linux kernel, the following vulnerability has been resolved: Input: gpio-keys - fix a sleep while atomic with PREEMPTRT When enabling PREEMPTRT, the gpiokeysirqtimer callback runs in hard irq context, but the inputevent takes a spinlock, which isn't allowed there as it is converted to a...

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 ...
