CVE-2024-27437

CVE-2024-27437 — Linux kernel (vfio/pci) intrinsic IRQ handling: The issue arises from auto-enabling of exclusive INTx IRQs during masking/unmasking, creating a window where an interrupt could fire and double-increment the disable depth. The fix in the sources inlines the kernel logic to never au...

CVE-2024-26813

The CVE-2024-26813 issue affects the Linux kernel vfio-platform subsystem (SET_IRQS) where loopback IRQ triggering can occur before an eventfd is configured, enabling a NULL dereference. The fix registers all IRQs in a disabled state during device open and ensures trigger changes are serialized w...
