  "details": "In the Linux kernel, the following vulnerability has been resolved:  zram: fix out-of-bounds access in read_block_state()  read_block_state() calculates nr_pages before taking dev_lock.  If the device is reset and reinitialized with a smaller disksize before lock acquisition, nr_pages still describes the old table.  The subsequent loop can then call slot_lock() past the end of the newly allocated table.  Read disksize after acquiring dev_lock and checking that the device is initialized.  The read lock then keeps the table and its bound stable for the duration of the scan.",
