CVE-2026-97478

The Linux kernel contains a use-after-free vulnerability within the acrn virtualization component. A race condition exists between acrn_irqfd_deassign() and the eventfd EPOLLHUP wakeup, which can cause both paths to free the same struct hsm_irqfd. This race may cause a work item to resurrect a da...
