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-2024-26812

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 ...
