05 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Create persistent INTx handler A vulnerability exists where the eventfd for INTx signaling can be deconfigured, which unregisters the IRQ handler but still allows eventfds to be signaled with a NULL context through the SET_IRQS ioctl or through unmask irqfd if the device interrupt is pending. Ideally this could be solved with some additional locking; the igate mutex serializes the ioctl and config space accesses, and the interrupt... • https://git.kernel.org/stable/c/89e1f7d4c66d85f42c3d52ea3866eb10cadf6153 • CWE-476: NULL Pointer Dereference •

05 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Lock external INTx masking ops Mask operations through config space changes to DisINTx may race INTx configuration changes via ioctl. Create wrappers that add locking for paths outside of the core interrupt code. In particular, irq_type is updated holding igate, therefore testing is_intx() requires holding igate. For example clearing DisINTx from config space can otherwise race changes of the interrupt configuration.
