2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------ From: Dan Carpenter <[email protected]> commit b652277b09d3d030cb074cc6a98ba80b34244c03 upstream. The "ct" variable should be an unsigned int. Both struct kbdiacrs ->kb_cnt and struct kbd_data ->accent_table_size are unsigned ints. Making it signed causes a problem in KBDIACRUC because the user could set the signed bit and cause a buffer overflow.
