CVE-2026-80971

A flaw was found in the ALSA bcd2000 driver of the Linux kernel. When a USB device using this driver is disconnected while a rawmidi substream is still active, the driver fails to clear the Universal Serial Bus Request Block URB pointers. This oversight allows a local attacker to trigger a...
