CVE-2026-89736

A flaw was found in the Linux kernel's USB audio gadget driver uaudio. This vulnerability occurs during sound card disconnection when Asynchronous Linux Sound Architecture ALSA control elements kctls remain open in userspace. A local attacker can exploit this timing issue by interacting with thes...

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...
