Subject: [PATCH] test/hash: avoid out of bound access
Date: Sat,  4 Jun 2022 10:37:11 +0200	[thread overview]
Message-ID: <20220604083711.64199-1-heinrich.schuchardt@canonical.com> (raw)

rwc_non_lf_results->multi_rw, rwc_lf_results->multi_rw, and
rwc_perf_results->multi_rw are accessed at indexes
[0..NUM_TEST-1][0..1][0..NUMTEST-1]. Currently the first index
overflows the array size in struct rwc_perf.

Fixes: c7eb0972e74b ("test/test/test_hash_readwrite_lf.c")
