Message-Id: <20220414161522.2320694-5-anthony.l.nguyen@intel.com> Date: Thu, 14 Apr 2022 09:15:22 -0700 From: Tony Nguyen <anthony.l.nguyen@...el.com> To: davem@...emloft.net, kuba@...nel.org, pabeni@...hat.com Cc: Jianglei Nie <niejianglei2021@....com>, netdev@...r.kernel.org, anthony.l.nguyen@...el.com, Gurucharan <gurucharanx.g@...el.com> Subject: [PATCH net 4/4] ice: Fix memory leak in ice_get_orom_civd_data() From: Jianglei Nie <niejianglei2021@....com> A memory chunk was allocated for orom_data in ice_get_orom_civd_data() by vzmalloc(). But when ice_read_flash_module() fails, the allocated memory is not freed, which will lead to a memory leak. We can fix it by freeing the orom_data when ce_read_flash_module() fails.
