Description

A flaw was found in the Linux kernel's Bluetooth L2CAP (Logical Link Control and Adaptation Protocol) module. This vulnerability, a null pointer dereference, occurs in the `l2cap_sock_ready_cb` function because it fails to validate if a pointer is null before attempting to use it. An attacker within Bluetooth range could potentially trigger this flaw, leading to a kernel panic and resulting in a Denial of Service (DoS) for the affected system.
