      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nzram: fix out-of-bounds access in read_block_state()\n\nread_block_state() calculates nr_pages before taking dev_lock.  If the\ndevice is reset and reinitialized with a smaller disksize before lock\nacquisition, nr_pages still describes the old table.  The subsequent loop\ncan then call slot_lock() past the end of the newly allocated table.\n\nRead disksize after acquiring dev_lock and checking that the device is\ninitialized.  The read lock then keeps the table and its bound stable for\nthe duration of the scan.",
