| Subject: CVE-2024-42150: net: txgbe: remove separate irq request for MSI and INTx |
| |
| Description |
| =========== |
| |
| 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. |
| |
| The Linux kernel CVE team has assigned CVE-2024-42150 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
