  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7915: release hif2 reference on probe IRQ failure\n\nThe hif2 reference obtained by mt7915_pci_init_hif2() is only released on\nerror paths that key off dev->hif2, which is not assigned until after the\nIRQ setup. If pci_alloc_irq_vectors() or the primary devm_request_irq()\nfails, the reference leaks. Drop it explicitly on those paths via\nmt7915_put_hif2().",
