      "title": "net: ngbe: fix NULL pointer dereference in non-MSI-X interrupt enabling",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ngbe: fix NULL pointer dereference in non-MSI-X interrupt enabling\n\nIn non-MSI-X mode (such as legacy INTx or single MSI), wx->msix_entry is\nnot allocated or initialized. Calling NGBE_INTR_MISC(wx) dereferences\nwx->msix_entry->entry, leading to a NULL pointer dereference crash.\n\nThis issue was introduced by fixing the IRQ vector when the number of\nVFs is 7. Fix the issue by explicitly checking `pdev->msix_enabled` to\ndetermine the correct vector index.\n\nAdditionally, as a side fix, set the interrupt mask to BIT(0) for the\nnon-MSI-X fallback. In MSI/INTx mode, the MISC and queue interrupts\nshare vector 0, and the WX_PX_MISC_IVAR register is only valid in the\nMSI-X case. Thus, BIT(0) is the correct mask for the miscellaneous cause\nwhen MSI-X is disabled.",
