From c957072d44a735ebbe8385fc3511a4f5e6ccea93 Mon Sep 17 00:00:00 2001 From: Thorsten Blum Date: Mon, 24 Nov 2025 13:54:53 +0100 Subject: [PATCH] x86/platform/olpc: Replace strcpy() with strscpy() in xo15_sci_add() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit strcpy() has been deprecated¹ because it performs no bounds checking on the destination buffer, which can lead to buffer overflows. Use the safer strscpy() instead. ¹ https://www.kernel.org/doc/html/latest/process/deprecated.html#strcpy Signed-off-by: Thorsten Blum Signed-off-by: Borislav Petkov (AMD) Link: https://patch.msgid.link/20251124125455.5495-2-thorsten.blum@linux.dev --- arch/x86/platform/olpc/olpc-xo15-sci.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/arch/x86/platform/olpc/olpc-xo15-sci.c b/arch/x86/platform/olpc/olpc-xo15-sci.c index 68244a3422d1d..82c51b6ec5288 100644 --- a/arch/x86/platform/olpc/olpc-xo15-sci.c +++ b/arch/x86/platform/olpc/olpc-xo15-sci.c @@ -7,6 +7,7 @@ #include #include +#include #include #include #include @@ -144,8 +145,8 @@ static int xo15_sci_add(struct acpi_device *device) if (!device) return -EINVAL; - strcpy(acpi_device_name(device), XO15_SCI_DEVICE_NAME); - strcpy(acpi_device_class(device), XO15_SCI_CLASS); + strscpy(acpi_device_name(device), XO15_SCI_DEVICE_NAME); + strscpy(acpi_device_class(device), XO15_SCI_CLASS); /* Get GPE bit assignment (EC events). */ status = acpi_evaluate_integer(device->handle, "_GPE", NULL, &tmp); -- 2.47.3
