CVE-2026-64601
In the Linux kernel, the following vulnerability has been resolved: ALSA: us144mkii: capture_urb_complete: redundant usb_anchor_urb corrupts anchor list on eac
In the Linux kernel, the following vulnerability has been resolved:
ALSA: us144mkii: capture_urb_complete: redundant usb_anchor_urb corrupts anchor list on each resubmission
In capture_urb_complete(), usb_anchor_urb() is called on every
completion callback, but the URB is already anchored from the
initial submission in tascam_trigger_start(). Each redundant call
corrupts the anchor's doubly-linked list and inflates the URB
refcount. When usb_kill_anchored_urbs() traverses the list during
stream stop / suspend / disconnect, the corrupted list leads to
use-after-free.
Remove the redundant usb_anchor_urb() from the resubmit path.
