Description OSIDB Bzimport 2026-08-15 06:33:19 UTC 
In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btmtk: fix URB leak in alloc_mtk_intr_urb error path

When btmtk_isopkt_pad() fails, the previously allocated URB is not freed,
leaking the urb structure. Add usb_free_urb() before returning the error.
