  "details": "In the Linux kernel, the following vulnerability has been resolved:  spi: use generic driver_override infrastructure  When a driver is probed through __driver_attach(), the bus' match() callback is called without the device lock held, thus accessing the driver_override 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 __driver_attach() without the device lock held is intentional. [1]  Also note that we do not enable the driver_override feature of struct bus_type, as SPI - in contrast to most other buses - passes \"\" to sysfs_emit() when the driver_override pointer is NULL. Thus, printing \"\\n\" instead of \"(null)\\n\".",
