In the Linux kernel, the following vulnerability has been resolved: usb: gadget: midi2: Fix the jack descriptor array sizes The jack in/out descriptor arrays in struct f_midi2_usb_config have the size of MAX_CABLES, which look reasonable -- but it turned out to be incorrect. Namely, the entries for those arrays are added from both inputs and outputs, hence for each loop cycle, it adds two, ended up with as twice as the expected size. This inconsistency may result in potential OOB when a large number of jacks are set up via configfs, although the max number of cables (the loop count) is limited to MAX_CABLES. For addressing it, correct the jack_ins & jack_outs array sizes to twice, MAX_CABLES * 2.
