CVE-2024-36968 is a denial-of-service vulnerability in the Linux kernel Bluetooth L2CAP implementation. The l2cap_le_flowctl_init() path used an LE MTU value that was not guaranteed to be within a valid range, permitting a zero divisor during LE flow-control initialization and allowing an integer-overflow condition. The corrected implementation validates the MTU during connection setup, stores validated MTU state on the HCI connection rather than the HCI device, terminates invalid connection processing earlier, and propagates failures from buffer-size handling and connection allocation.
