"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nspi: 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. [1]\n\nAlso note that we do not enable the driver_override feature of struct\nbus_type, as SPI - in contrast to most other buses - passes \"\" to\nsysfs_emit() when the driver_override pointer is NULL. Thus, printing\n\"\\n\" instead of \"(null)\\n\"."
