CVE-2018-20961
In the Linux kernel before 4.16.4, a double free vulnerability in the f_midi_set_alt function of drivers/usb/gadget/function/f_midi.c in the f_midi driver may allow attackers to cause a denial of service or possibly have unspecified other impact.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.34%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
