From a2ea6ed6a631e24d315b5f2bd468e6f4c7ff2e48 Mon Sep 17 00:00:00 2001 From: Christian Engelmayer Date: Mon, 21 Apr 2014 20:46:40 +0200 Subject: crypto: tcrypt - Fix potential leak in test_aead_speed() if crypto_alloc_aead() fails Fix a potential memory leak in the error handling of test_aead_speed(). In case crypto_alloc_aead() fails, the function returns without going through the centralized cleanup path. Reported by Coverity - CID 1163870.
