Subject: [PATCH] ath11k: fix invalid memory access
Date: Fri, 21 Jun 2019 00:26:13 +0530 [thread overview]
Message-ID: <1561056973-32524-1-git-send-email-periyasa@codeaurora.org> (raw)
dp_reo_cache_flush_elem element get dynamically allocated with invalid size
which leads to the access of unallocated memory region or memory corruption.
Fix this bug by allocate with dp_reo_cache_flush_elem structure size.
