It is possible that the context with the freed buffers is # reused. In case of an error during initialization where the pointers # do not yet point to allocated memory, the NULL value prevents a double # free. # # Cc: stable@vger.kernel.org # Fixes: 3cfc3b9721123 ("crypto: drbg - use aligned buffers") # Signed-off-by: Stephan Mueller # Reported-by: syzbot+75397ee3df5c70164154@syzkaller.appspotmail.com # Signed-off-by: Herbert Xu # < /opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux-gcc --version # < git log --format=%s --max-count=1 eea0d3ea7546961f69f55b26714ac8fd71c7c020 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/crypto_powernv_defconfig_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- powernv_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/crypto_powernv_defconfig_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- WARNING: modpost: Found 2 section mismatch(es).
