## Description

In the Linux kernel, the following vulnerability has been resolved:  ima: Fix stack-out-of-bounds in is_bprm_creds_for_exec()  KASAN reported a stack-out-of-bounds access in ima_appraise_measurement from is_bprm_creds_for_exec:  BUG: KASAN: stack-out-of-bounds in ima_appraise_measurement+0x12dc/0x16a0  Read of size 1 at addr ffffc9000160f940 by task sudo/550 The buggy address belongs to stack of task sudo/550 and is located at offset 24 in frame:   ima_appraise_measurement+0x0/0x16a0 This frame has 2 objects:   [48, 56) 'file'   [80, 148) 'hash'  This is caused by using container_of on the *file pointer. This offset calculation is what triggers the stack-out-of-bounds error.  In order to fix this, pass in a bprm_is_check boolean which can be set depending on how process_measurement is called. If the caller has a linux_binprm pointer and the function is BPRM_CHECK we can determine is_check and set it then. Otherwise set it to false.
