Subject: [dpdk-dev] [PATCH] baseband/turbo_sw: fix dereference of null
Date: Thu, 22 Apr 2021 17:25:05 +0800 [thread overview]
Message-ID: <1619083505-65454-1-git-send-email-humin29@huawei.com> (raw)
Return value of a function 'rte_malloc' is dereferenced without
checking, and may result in segmetation fault.
This patch fixed it.
Fixes: 31a7853d1ed9 ("baseband/turbo_sw: support large size code block")
Cc: stable@dpdk.org
