Here are 2 patches against the 'usb-next' branch of Greg KH's 'usb.git' repo. The UHCI driver's debugging code uses a lot of sprintf() calls with the large buffers, leaving some space at the end of the buffers to handle the buffer overflow. Using scnprntf() calls instead eliminates the very possibility of the buffer overflow... Sergey Shtylyov (2): usb: host: uhci-debug: use scnprintf() instead of sprintf() usb: host: uhci: remove #define EXTRA_SPACE drivers/usb/host/uhci-debug.c | 263 ++++++++++++---------------------- drivers/usb/host/uhci-hcd.c | 2 +- drivers/usb/host/uhci-q.c | 2 +- 3 files changed, 93 insertions(+), 174 deletions(-) -- 2.26.3
