Doc Text: |
A use-after-free flaw was found in the Linux kernel's implementation of logical link control and adaptation protocol (L2CAP), part of the Bluetooth stack in the l2cap_connect and l2cap_le_connect_req functions. An attacker with physical access within the range of standard Bluetooth transmission could execute code leaking kernel memory via Bluetooth if within proximity of the victim.
