CVE-2025-40282

In CVE-2025-40282, the Linux kernel Bluetooth 6lowpan implementation (net/bluetooth/6lowpan.c) is affected. The issue arises because netdev header_ops requires a link-local MAC header on RX skb, but the code resets this header only for the uncompressed IPv6 RX path; the compressed path already ha...
