EUVD-2026-86659

In the Linux kernel, the following vulnerability has been resolved: ALSA: caiaq: Decoupling ep1inurb in caiaq dev The epqinurb object belonging to the caiaq device is coupled within the struct sndusbcaiaqdev. After usbsubmiturbepqinurb, GFPKERNEL executes successfully, epqinurb is successfully...

CVE-2026-98006

The Linux kernel contains a use-after-free vulnerability in the ALSA caiaq USB device driver. The issue arises because the ep1_in_urb (and midi_out_urb) objects are embedded within the snd_usb_caiaqdev structure. When a command fails due to a timeout and snd_card_free() is called to release the c...
