"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: au1000: move free_irq out of the close-time spinlocked section\n\nau1000_close() calls free_irq() while aup->lock is still held with\nspin_lock_irqsave(). free_irq() can sleep because it takes the IRQ\ndescriptor request mutex, so it does not belong inside the close-time\nspinlocked section.\n\nThis was found by our static analysis tool and then confirmed by manual\nreview of the in-tree au1000_close() .ndo_stop path. The reviewed path\nkeeps aup->lock held across the MAC reset, queue stop and\nfree_irq(dev->irq, dev).\n\nA directed runtime validation kept that ndo_stop carrier and the same\nfree_irq(dev->irq, dev) operation under the driver lock. Lockdep reported\n\"BUG: sleeping function called from invalid context\" and \"Invalid wait\ncontext\" while free_irq() was taking desc->request_mutex, with\nau1000_close() and free_irq() on the stack.\n\nDrop aup->lock before freeing the IRQ. The protected close-time work still\nstops the device and queue before IRQ teardown, but the sleepable IRQ core\npath now runs outside the spinlocked section."
