Subject: A potential issue in security_inode_init_security function
Date: Fri, 29 Sep 2017 20:37:57 +0800 [thread overview]
Message-ID: <cedbcdd2-ef0c-afa9-627a-406ed0712af8@huawei.com> (raw)
In security_inode_init_security function of security/security.c, lsm_xattr can be modified by multiple functions due to call_init_hook function. I think that it is a potential issue when inode_init_security list is associated with more security modules, although inode_init_security list is associated with only selinux and smack currrently and the two security modules usually are not used at the same time.
