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...

CVE-2026-80969

CVE-2026-80969 affects the Linux kernel 's ALSA mpu401 driver. At probe time, the driver blindly trusts the devptr->id value as a valid card index. While this is safe for devices created during normal module probe, if a device is bound manually via sysfs , the value can be -1 ("none"), leading...

CVE-2026-80970

CVE-2026-80970 affects the Linux kernel ALSA FCP USB audio driver. In fcp_ioctl_init(), the response buffer is allocated via kmalloc() without being zeroed. Because the step-0 USB control transfer does not set URB_SHORT_NOT_OK, a short or zero-length data stage is accepted as success, and snd_usb...
