ERR_PTR is not NULL, so\nintegrity_audit_message() sees a valid pointer and calls strlen() on\nit, which faults:\n\n    BUG: unable to handle page fault for address: ffffffffffffffdc\n    RIP: 0010:strlen+0x30/0xa0\n    Call Trace:\n     audit_log_untrustedstring+0x19/0x30\n     integrity_audit_message+0x366/0x4f0\n     ima_inode_setxattr+0x512/0x5f0\n\nCheck for IS_ERR() and use NULL instead, which makes the audit message\nskip the name= field instead of crashing.",
