"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ns390/dasd: Do not complete a failed ESE read as successful\n\ndasd_int_handler() completes an NRF read of an unallocated ESE track by\ncalling ese_read() and unconditionally marking the request\nDASD_CQR_SUCCESS. dasd_eckd_ese_read() can return an error before it has\nzeroed the destination buffer: a failed sense-data parse or a current\ntrack outside the requested range both return early, leaving the\ndestination pages untouched. The request is still completed successfully,\nso the block layer is handed stale / uninitialized memory instead of\nzeros.\n\nCheck the ese_read() return value and fail the request through the normal\nerror path instead of forcing DASD_CQR_SUCCESS."
