CVE-2026-64429

In the Linux kernel, the following vulnerability has been resolved: gpio: eic-sprd: use raw_spinlock_t in the irq startup path sprd_eic_irq_unmask() enables the GPIO IRQ and then updates controller state through sprd_eic_update(), which takes sprd_eic->lock with spin_lock_irqsave(). The callback can be reached from irq_startup() while setting up a requested IRQ. That path is not sleepable, but on PREEMPT_RT a regular spinlock_t becomes a sleeping lock. This issue was found by our static ana
