Description OSIDB Bzimport 2026-08-15 06:40:45 UTC
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.
