Description
A flaw was found in the Linux kernel's Bluetooth Low Energy (LE) subsystem. When multiple LE connection attempts are made concurrently, and one connection fails, the system may not properly release the failed connection's resources. This resource leak can prevent all subsequent outgoing LE connection attempts from succeeding, effectively causing a denial of service for Bluetooth LE functionality until the adapter is reset.
