A vulnerability in the Linux kernel's Bluetooth 6lowpan subsystem was fixed by adding a check for the return value of skb_clone() in the send_mcast_pkt() function. Without this check, a NULL pointer dereference could occur if skb_clone() fails due to memory allocation issues. This flaw could lead to kernel crashes or instability. The issue affects multiple linux-aws kernel versions prior to 7.0.0-28.28~24.04.1 and related versions. A patch is available and should be applied to mitigate the risk.
