Description OSIDB Bzimport 2024-07-30 08:39:48 UTC

In the Linux kernel, the following vulnerability has been resolved:

net: txgbe: remove separate irq request for MSI and INTx

When using MSI or INTx interrupts, request_irq() for pdev->irq will
conflict with request_threaded_irq() for txgbe->misc.irq, to cause
system crash. So remove txgbe_request_irq() for MSI/INTx case, and
rename txgbe_request_msix_irqs() since it only request for queue irqs.

Add wx->misc_irq_domain to determine whether the driver creates an IRQ
domain and threaded request the IRQs.
