From ad2fdcdf75d169e7a5aec6c7cb421c0bec8ec711 Mon Sep 17 00:00:00 2001 From: Tudor-Dan Ambarus Date: Tue, 3 Apr 2018 09:39:00 +0300 Subject: [PATCH] crypto: authenc - don't leak pointers to authenc keys In crypto_authenc_setkey we save pointers to the authenc keys in a local variable of type struct crypto_authenc_keys and we don't zeroize it after use. Fix this and don't leak pointers to the authenc keys.
