CVE-2026-64428

CVE-2026-64428 affects the SCH GPIO controller (gpio:sch) in the Linux kernel. The root cause is that sch_irq_unmask() acquires sch->lock via spin_lock_irqsave(), which on PREEMPT_RT becomes a sleeping lock. This lock is reached from irq_startup(), a non-sleepable context, triggering a "sleepi...
