DescriptionIn the Linux kernel, the following vulnerability has been resolved: arm64: Set __nocfi on swsusp_arch_resume() A DABT is reported[1] on an android based system when resume from hiberate. This happens because swsusp_arch_suspend_exit() is marked with SYM_CODE_*() and does not have a CFI hash, but swsusp_arch_resume() will attempt to verify the CFI hash when calling a copy of swsusp_arch_suspend_exit(). Given that there's an existing requirement that the entrypoint to swsusp_arch_suspend_exit() is the first byte of the .hibernate_exit.text section, we cannot fix this by marking swsusp_arch_suspend_exit() with SYM_FUNC_*(). The simplest fix for now is to disable the CFI check in swsusp_arch_resume(). Mark swsusp_arch_resume() as __nocfi to disable the CFI check.
