Summary
CVE-2026-80676 affecting package kernel 6.6.150.1-1
Details

In the Linux kernel, the following vulnerability has been resolved:

Drivers: hv: vmbus: use generic driver_override infrastructure

When a driver is probed through __driverattach(), the bus' match() callback is called without the device lock held, thus accessing the driveroverride field without a lock, which can cause a UAF.

Fix this by using the driver-core driver_override infrastructure taking care of proper locking internally.

Note that calling match() from _driverattach() without the device lock held is intentional. [1]
