CVE-2026-80676

A flaw was found in the Linux kernel's Hyper-V hv VMBus driver. When a driver is being initialized, a specific callback function attempts to access a memory region driveroverride without proper synchronization. This oversight can lead to a Use-After-Free UAF vulnerability, where a local attacker...

CVE-2026-80676

CVE-2026-80676 affects the Linux kernel Hyper-V vmbus driver. When a driver is probed via __driver_attach(), the bus match() callback is invoked without the device lock held, allowing an unlocked access to the driver_override field that can lead to a Use-After-Free (UAF) condition. The fix migrat...
