"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: eic-sprd: use raw_spinlock_t in the irq startup path\n\nsprd_eic_irq_unmask() enables the GPIO IRQ and then updates controller\nstate through sprd_eic_update(), which takes sprd_eic->lock with\nspin_lock_irqsave(). The callback can be reached from irq_startup()\nwhile setting up a requested IRQ. That path is not sleepable, but on\nPREEMPT_RT a regular spinlock_t becomes a sleeping lock.\n\nThis issue was found by our static analysis tool and then manually\nreviewed against the current tree.\n\nThe grounded PoC kept the request_threaded_irq() -> __setup_irq() ->\nirq_startup() -> sprd_eic_irq_unmask() -> sprd_eic_update() carrier and\nused the original spin_lock_irqsave(&sprd_eic->lock) edge. Lockdep\n\n BUG: sleeping function called from invalid context\n hardirqs last disabled at ... __setup_irq.constprop.0 ... [vuln_msv]\n sprd_rt_spin_lock_irqsave+0x1c/0x30 [vuln_msv]\n sprd_eic_update.constprop.0+0x48/0x90 [vuln_msv]\n sprd_eic_irq_unmask.constprop.0+0x35/0x50 [vuln_msv]\n __setup_irq.constprop.0+0xd/0x30 [vuln_msv]\n\nConvert the Spreadtrum EIC controller lock to raw_spinlock_t. The\nlocked section only serializes MMIO register updates and does not contain\nsleepable operations, so keeping it non-sleeping is appropriate for the\nirqchip callbacks."
