Description

A flaw was found in the Linux kernel's Bluetooth L2CAP (Logical Link Control and Adaptation Protocol) implementation. This vulnerability arises from an incorrect order of acquiring locks during channel cleanup, which could lead to a race condition. This issue could potentially cause instability or unexpected behavior within the Bluetooth subsystem. The fix involves using a channel timer to close channels asynchronously, ensuring proper lock acquisition.
