      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ns390/dasd: Propagate partial completion length across ERP recovery\n\ndasd_default_erp_postaction() copies the timing and device state from\nthe finished ERP request back to the original request but drops\nproc_bytes. A request that was partially completed, an ESE read of a\nnot-yet-allocated track returns fewer bytes than requested, and then\nrecovered through the ERP chain loses its partial-completion length.\n__dasd_cleanup_cqr() then sees proc_bytes == 0 and completes the whole\nrequest instead of requeueing the remainder, silently returning zeroed\ndata for the part that was never read.\n\nCarry proc_bytes over to the original request like the other\nper-request state.",
