The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In the Linux kernel, the following vulnerability has been resolved: schedext: Replace rqlock to rawspinrqlock in scxopsbypass scxopsbypass iterates all CPUs to...

kernel: rcu-tasks: Avoid pr_info() with spin lock in cblist_init_generic()

A locking violation was found in the Linux kernel RCU-tasks subsystem's callback list initialization. During system boot, the initialization code calls prinfo while holding the rtp-cbsgbllock spinlock, causing a potentially sleeping function to be called in atomic context, which results in kernel...

DEBIAN-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 ...
