CVE-2026-80896

CVE-2026-80896 affects the mshv (Microsoft Hyper-V) component of the Linux kernel . The root cause is a race condition in mshv_irqfd_deassign(): it traverses pt_irqfds_list without holding the required pt->pt_irqfds_lock spinlock, racing with the EPOLLHUP path in mshv_irqfd_wakeup(). A second ...
