{"id":"CVE-2026-80676","summary":"Drivers: hv: vmbus: use generic driver_override infrastructure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nDrivers: hv: vmbus: use generic driver_override infrastructure\n\nWhen a driver is probed through __driver_attach(), the bus' match()\ncallback is called without the device lock held, thus accessing the\ndriver_override field without a lock, which can cause a UAF.\n\nFix this by using the driver-core driver_override infrastructure taking\ncare of proper locking internally.\n\nNote that calling match() from __driver_attach() without the device lock\nheld is intentional.
