Description
A flaw was found in the Linux kernel's wifi: mt76: mt7915 driver. During the probe interrupt (IRQ) setup, if the pci_alloc_irq_vectors() or devm_request_irq() functions fail, a hif2 reference is not properly released. This oversight results in a resource leak, which could potentially lead to system instability or a denial of service (DoS).
