  "summary": "block: mtip32xx: synchronize ioctls with device removal",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nblock: mtip32xx: synchronize ioctls with device removal\n\nThe ioctl handlers only test REMOVE_PENDING before entering\nmtip_hw_ioctl(). Removal can set that bit immediately afterwards and free\ndd->port in mtip_hw_exit() while an ioctl still dereferences it. An already\nopen block device can reach the handlers while del_gendisk() is in\nprogress.\n\nSerialize both native and compat ioctls with removal. Set REMOVE_PENDING\nbefore taking the mutex so new callers fail after an in-flight ioctl has\ndrained, and hold the mutex until the port has been torn down.",
