In the Linux kernel, the following vulnerability has been resolved: NTB: epf: Avoid calling pciirqvector from hardirq context ntbepfvecisr calls pciirqvector in hardirq context to derive the vector number. pciirqvector calls msigetvirq that takes a mutex and can therefore trigger "scheduling whil...

CVE-2026-64430

CVE-2026-64430 affects the Linux kernel NTB EPF subsystem. ntb_epf_vec_isr previously called pci_irq_vector() in hardirq context, and pci_irq_vector() may call msi_get_virq() which takes a mutex and can trigger scheduling while atomic. The fix caches the Linux IRQ number for vector 0 when vectors...
