CVE-2026-98770

The Linux kernel contains a vulnerability in the usb gadget midi2 component. Specifically, the jack_ins and jack_outs descriptor arrays in struct f_midi2_usb_config were incorrectly sized to MAX_CABLES. Because entries are added from both inputs and outputs during loop cycles, the arrays actually...
