  "title": "gpio: eic-sprd: use raw_spinlock_t in the irq startup path",
  "description": "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-\u003Elock 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 analysis tool and then manually reviewed against the current tree.  The grounded PoC kept the request_threaded_irq() -\u003E __setup_irq() -\u003E irq_startup() -\u003E sprd_eic_irq_unmask() -\u003E sprd_eic_update() carrier and used the original spin_lock_irqsave(\u0026sprd_eic-\u003Elock) edge.  Lockdep    BUG: sleeping function called from invalid context   hardirqs last disabled at ... __setup_irq.constprop.0 ... [vuln_msv]   sprd_rt_spin_lock_irqsave\u002B0x1c/0x30 [vuln_msv]   sprd_eic_update.constprop.0\u002B0x48/0x90 [vuln_msv]   sprd_eic_irq_unmask.constprop.0\u002B0x35/0x50 [vuln_msv]   __setup_irq.constprop.0\u002B0xd/0x30 [vuln_msv]  Convert the Spreadtrum EIC controller lock to raw_spinlock_t.  The locked section only serializes MMIO register updates and does not contain sleepable operations, so keeping it non-sleeping is appropriate for the irqchip callbacks.",
