Description

A flaw was found in the Linux kernel's Bluetooth USB (btusb) driver. An attacker with control over Bluetooth connections could trigger an out-of-bounds read in the `btusb_work()` function. This occurs because the function, which maps active Synchronous Connection-Oriented (SCO) links to USB alternate settings, uses an unconstrained index when accessing an internal lookup table. This vulnerability could lead to system instability or a denial of service.
