5 | |||
6 | commit 8f3fafc9c2f0ece10832c25f7ffcb07c97a32ad4 upstream. | ||
7 | |||
8 | Like d88b6d04: "cdrom: information leak in cdrom_ioctl_media_changed()" | ||
9 | |||
10 | There is another cast from unsigned long to int which causes | ||
11 | a bounds check to fail with specially crafted input. The value is | ||
12 | then used as an index in the slot array in cdrom_slot_status(). | ||
