| H A D | lrw.c | diff fbe1a850b3b1522e9fc22319ccbbcd2ab05328d2 Thu Sep 13 10:51:31 CEST 2018 Ondrej Mosnacek <omosnace@redhat.com> crypto: lrw - Fix out-of bounds access on counter overflow
When the LRW block counter overflows, the current implementation returns
128 as the index to the precomputed multiplication table, which has 128
entries. This patch fixes it to return the correct value (127).
