In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
s390\/dasd: Propagate partial completion length across ERP recovery<\/p>\n
dasd_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.<\/p>\n
Carry proc_bytes over to the original request like the other
\nper-request state.<\/p>\n","protected":false},"excerpt":{"rendered":"
