      "title": "uio: Fix stale info pointer in failed registration path",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nuio: Fix stale info pointer in failed registration path\n\nAfter device_add(), the UIO device is visible to userspace and /dev/uioX\ncan be opened. If a later setup step fails, __uio_register_device()\nunwinds the device but leaves idev->info pointing at the caller-owned\nstruct uio_info.\n\nThat is unsafe when an opener races with the failed registration path.\nThe open file keeps a reference to the uio_device, while the caller sees\nregistration failure and may free its struct uio_info. Later file\noperations can then follow idev->info and dereference freed memory.\n\nHandle post-device_add() failures like unregister: remove UIO attributes\nwhile the info pointer is still valid, then clear idev->info under\ninfo_lock and wake existing waiters/async users before removing the\ndevice and minor. This makes already-open file descriptors observe the\nsame \"device gone\" state as normal uio_unregister_device().",
