In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7921: fix resource leak in probe error path
When pcim_iomap_region() or devm_kmemdup() fail, the code returns
directly without cleaning up previously allocated resources:
- mt76_device allocated by mt76_alloc_device()
- pci irq vectors allocated by pci_alloc_irq_vectors()
Fix this by jumping to the existing error cleanup path instead of
returning directly.
