CVE-2026-80971

CVE-2026-80971 is a use-after-free vulnerability in the ALSA bcd2000 driver (snd_bcd2000) of the Linux kernel. On USB device disconnect, bcd2000_free_usb_related_resources() frees both MIDI URBs without clearing the pointers. A still-open rawmidi substream can then access the freed URBs via the t...
