From: Li Huafei <lihuafei1@huawei.com> Offering: HULK hulk inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I6KT9C CVE: CVE-2023-1249 -------------------------------- The coredump_params structure is only used as parameters for function pointer members of some structures, such as linux_binfmt, spufs_calls, etc., and the parameters are of pointer type, so adding members of coredump_params will not affect the memory layout. Also coredump_params is used to hold coredump parameters to be passed to coredump functions of different types of binfmt, the driver will not use the structure.
