CVE-2024-26814 vfio/fsl-mc: Block calling interrupt handler without trigger

In the Linux kernel, the following vulnerability has been resolved: vfio/fsl-mc: Block calling interrupt handler without trigger The eventfdctx trigger pointer of the vfiofslmcirq object is initially NULL and may become NULL if the user sets the trigger eventfd to -1. The interrupt handler itself...

CVE-2024-26814

CVE-2024-26814 affects the Linux kernel vfio-fsl-mc driver. The eventfd_ctx trigger pointer for vfio_fsl_mc_irq can be NULL and may become NULL if the trigger is set to -1. The interrupt handler itself is guaranteed to have a valid trigger between request_irq() and free_irq(), but loopback tests ...

CVE-2024-26812

VFIO PCI: Create persistent INTx handler. The described issue allowed signaling an INTx eventfd with a NULL context via SET_IRQS or unmask irqfd even when the IRQ handler was unregistered. The connected documents state that the fix moves INTx interrupt handler configuration to track the lifetime ...

CVE-2024-26812 vfio/pci: Create persistent INTx handler

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...

CVE-2024-26810

CVE-2024-26810 (Linux kernel) concerns the vfio/pci path where masking operations for external INTx were not properly synchronized with INTx configuration changes. The description in the initial document notes a race between config-space changes to DisINTx and ioctl-driven updates to interrupt co...
