Yuntao Wang 2ef607ea10 init/main.c: Fix potential static_command_line memory overflow ... commit 46dad3c1e5 upstream. We allocate memory of size 'xlen + strlen(boot_command_line) + 1' for static_command_line, but the strings copied into static_command_line are extra_command_line and command_line, rather than extra_command_line and boot_command_line. When strlen(command_line) > strlen(boot_command_line), static_command_line will overflow. This patch just recovers strlen(command_line) which was miss-consolidated with strlen(boot_command_line) in the commit f5c7310ac7 ("init/main: add checks for the return value of memblock_alloc*()") Link: https://lore.kernel.org/all/20240412081733.35925-2-ytcoode@gmail.com/ Fixes: f5c7310ac7 ("init/main: add checks for the return value of memblock_alloc*()") Cc: stable@vger.kernel.org Signed-off-by: Yuntao Wang <ytcoode@gmail.com> Signed-off-by: Masami Hiramatsu (Google) <mhiramat@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2024-05-02 16:23:39 +02:00
