CVE-2026-80972

This vulnerability affects the ALSA aloop driver in the Linux kernel . The driver blindly trusts the devptr->id value as a valid card index at probe time. While this is safe for devices created during module probe, if a device is bound manually via the sysfs interface , the index can be -1 ("n...

CVE-2026-80973

CVE-2026-80973 affects the Linux kernel's ALSA snd_usb_6fire driver. In usb6fire_comm_receiver_handler(), a MIDI event length byte supplied by the USB device is used without bounding it or checking urb->actual_length. The receiver_buffer is a 64-byte allocation (2-byte header + 62 usable bytes...

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...
